Title:A reversible data hiding method based on bitmap prediction for AMBTC compressed hyperspectral images
Author Full Names:Zhang, Xiaoran(1,2); Pan, Zhibin(2,5); Zhou, Quan(3); Fan, Guojun(2); Dong, Jing(4)Source Title:Journal of Information Security and ApplicationsLanguage:EnglishDocument Type:Journal article (JA)Abstract:In the transmission of hyperspectral images that have been compressed using absolute moment block truncation coding (AMBTC), confidentiality and security of crucial information is often a concern. Although many data hiding (DH) methods based on AMBTC work well in guaranteeing a large amount of secret information can be embedded, the requirements of actual user scenarios, such as reversibility and imperceptibility, are degraded sometimes. To address these challenges, we propose an embedding pattern that utilizes bitmap prediction to embed secret information within the bitmaps while preserving the standard format of AMBTC codes and enabling recovery of the cover image without loss. Our proposed method, therefore, belongs to the category of reversible data hiding (RDH) techniques. Since the embedding distortion (ED) reduction is an essential object, an adaptive embedding order based on the features of AMBTC codes is conducted. Furthermore, we propose a dynamical embedding scheme to reduce ED when we are striving to achieve a larger embedding capacity (EC). ? 2024 Elsevier LtdAffiliations:(1) Nanjing Power Supply Company, State Grid Jiangsu Electric Power Co., Ltd., Jiangsu, Nanjing; 210019, China; (2) Faculty of Electronic and Information Engineering, Xi'an Jiaotong University, Shaanxi, Xi'an; 710049, China; (3) National Key Laboratory of Science and Technology on Space Microwave, Xi'an Institute of Space Radio Technology, Shaanxi, Xi'an; 710100, China; (4) National Laboratory of Pattern Recognition, Institute of Automation, Chinese Academy of Sciences, Beijing; 100190, China; (5) State Key Laboratory of Transient Optics and Photonics, Chinese Academy of Sciences, Beijing; 100190, ChinaPublication Year:2024Volume:81Article Number:103697DOI Link:10.1016/j.jisa.2023.103697數(shù)據(jù)庫ID（收錄號(hào)）:20240315396843 -

Title:Design and optimization of cryogenic installation structure for gratings of Long-wave Infrared Spatial Heterodyne Interferometer
Author Full Names:Wu, Yang(1,2); Feng, Yutao(1); Han, Bin(1,2); Wu, Junqiang(1); Sun, Jian(1,2)Source Title:Guangxue Jingmi Gongcheng/Optics and Precision EngineeringLanguage:ChineseDocument Type:Journal article (JA)Abstract:The Long-wave Infrared Spatial Heterodyne Interferometer may have interference fringe distortion due to non-uniform stress acting on the optical components under cryogenic conditions，which will cause performance degradation of the interferometer system. To solve the problem of interference fringe distortion under cryogenic conditions，this paper analyzed the factors affecting interference fringe distortion based on the initial optical mechanical system of Long-wave infrared spatial heterodyne interferometer，and combined the optical-mechanical-thermal coupling analysis method to simulate the cryogenic state of the interferometer system. Then，a cryogenic micro-stress dynamic stable installation structure was designed for grating，which is the key component affecting fringe distortion. After the optimization of structure，the Root-Mean-Square（RMS）and Peak-to-Valley（PV）values of grating’s surface shape are 3. 89×10-2 nm and 2. 21×10-1 nm，respectively，which are five orders of magnitude lower than the initial structure analysis results. The simulated interference fringe distortion is less than 1 detector pixel. The cryogenic verification test of whole system shows that the optimized structure can effectively reduce the distortion of interference fringe，and the distortion is less than 2 detector pixels. The experimental results are highly consistent with the simulation results，which verifies the effectiveness of the optimization analysis method. The optimization analysis method has great significance and value for improving the structural stability and operating performance of the cryogenic reflective optical system. ? 2024 Chinese Academy of Sciences.

Title:Investigation on multi-objective optimization for in-situ laser-assisted machining of glass-ceramic
Author Full Names:Fan, Mingxu(1); Sun, Guoyan(1); Ding, Jiaoteng(1); Song, Jinzhou(2)Source Title:Applied Physics A: Materials Science and ProcessingLanguage:EnglishDocument Type:Journal article (JA)Abstract:As a typical optical hard and brittle material, the efficient machining methods of glass-ceramic have always been a research hotspot. Based on previous research, this article conducted surface damage analysis on glass-ceramic using in-situ laser-assisted machining (LAM) orthogonal experimental results, and summarized that the surface damage of glass-ceramic mainly includes scratches, pits, and brittle fracture. Surface analysis confirmed that in-situ LAM can effectively reduce cutting forces and improve surface quality compared to conventional cutting. The artificial neural network (ANN) and genetic algorithm (GA) were used to fit and train and conduct multi-objective optimization for the data from in-situ LAM orthogonal experiments with resultant cutting force and surface roughness as eigenvalues. The Pareto optimal front curve with multiple groups of optimal solutions was obtained through multi-objective optimization using GA. The actual in-situ LAM experimental values were compared with the predicted values in the Pareto front, the relative error of the resultant force and the relative error of the surface roughness are both very small. In-situ LAM experiments based on response surface methodology (RSM) with surface roughness as the characteristic value were conducted. The optimal machining parameters for RSM optimization, as well as the minimum values for resultant force and surface roughness were obtained. Through comparative analysis, it was found that RSM has better multi-objective optimization performance than GA. Research content of this article provides reference and guidance for the multi-objective optimization analysis method of hard and brittle materials such as glass-ceramic after LAM. ?

Title:Optical design of a 5× zoom afocal telescope with deformable mirrors
Author Full Names:Zou, Gangyi(1,2); Fan, Xuewu(1); Zhao, Hui(1); Pang, Zhihai(1); Xie, Xiaopeng(1); Xu, Liang(1)Source Title:Optics ExpressLanguage:EnglishDocument Type:Journal article (JA)Abstract:All-reflective zoom afocal telescopes can be integrated with existing imaging systems as foreoptics, enabling flexible imaging with adjustable resolution. This paper proposes an approach to designing a 5× zoom afocal telescope using deformable mirrors. Based on matrix optics, the first-order parameters for a coaxial reflective 5× zoom afocal telescope with a fixed primary mirror and three deformable mirrors are determined. To prevent obscuration, the mirrors are tilted at their vertices, which introduces asymmetric aberrations. To correct these aberrations, XY polynomial surfaces are employed on the primary mirror and an additional flat fold mirror. The final design and image simulations indicate that the system achieves good image quality across all zoom positions, enabling 5× zoom imaging with a maximum root mean square wavefront error of less than 0.125λ (λ = 632.8 nm), thereby validating the efficacy of the proposed design methodology. ? 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.Affiliations:(1) Space Optics Laboratory, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi’an; 710119, China; (2) University of Chinese Academy of Sciences, Beijing; 100049, ChinaPublication Year:2024Volume:32Issue:20Start Page:34622-34638DOI Link:10.1364/OE.537331數(shù)據(jù)庫ID（收錄號(hào)）:20244017148692 -

Title:Rapid Determination of Positive–Negative Bacterial Infection Based on Micro-Hyperspectral Technology
Author Full Names:Du, Jian(1,2); Tao, Chenglong(1,2); Qi, Meijie(1,2); Hu, Bingliang(1,2); Zhang, Zhoufeng(1,2)Source Title:SensorsLanguage:EnglishDocument Type:Journal article (JA)Abstract:To meet the demand for rapid bacterial detection in clinical practice, this study proposed a joint determination model based on spectral database matching combined with a deep learning model for the determination of positive–negative bacterial infection in directly smeared urine samples. Based on a dataset of 8124 urine samples, a standard hyperspectral database of common bacteria and impurities was established. This database, combined with an automated single-target extraction, was used to perform spectral matching for single bacterial targets in directly smeared data. To address the multi-scale features and the need for the rapid analysis of directly smeared data, a multi-scale buffered convolutional neural network, MBNet, was introduced, which included three convolutional combination units and four buffer units to extract the spectral features of directly smeared data from different dimensions. The focus was on studying the differences in spectral features between positive and negative bacterial infection, as well as the temporal correlation between positive–negative determination and short-term cultivation. The experimental results demonstrate that the joint determination model achieved an accuracy of 97.29%, a Positive Predictive Value (PPV) of 97.17%, and a Negative Predictive Value (NPV) of 97.60% in the directly smeared urine dataset. This result outperformed the single MBNet model, indicating the effectiveness of the multi-scale buffered architecture for global and large-scale features of directly smeared data, as well as the high sensitivity of spectral database matching for single bacterial targets. The rapid determination solution of the whole process, which combines directly smeared sample preparation, joint determination model, and software analysis integration, can provide a preliminary report of bacterial infection within 10 min, and it is expected to become a powerful supplement to the existing technologies of rapid bacterial detection. ? 2024 by the authors.Affiliations:(1) Key Laboratory of Spectral Imaging Technology CAS, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi’an; 710119, China; (2) Xi’an Key Laboratory for Biomedical Spectroscopy, Xi’an; 710119, ChinaPublication Year:2024Volume:24Issue:2Article Number:507DOI Link:10.3390/s24020507數(shù)據(jù)庫ID（收錄號(hào)）:20240515462384 -

When FFT is applied in analyzing signal frequency bands that cannot be densely sampled, the frequency resolution obtained will be relatively low. Applying the Chirp-Z Transform (CZT) to the near-far field transformation highlights the characteristic of the CZT that allows the input points to be equally angle-sampled and then resampled. This expands the sampling quantity to any integer length. By using CZT, the antenna measurement points can be sampled and transformed into an arbitrary number of frequency points. This approach can change the resolution of sample points in the near-far field transformation, allowing for frequency spectrum refinement in specific narrow frequency bands. ? 2024 IEEE.Affiliations:(1) Xinjiang University, School of Mechanical Engineering, Urumqi, China; (2) Xi'an Institute of Optics and Precision Mechanics of CAS, Space Optics Technology Department, Xi'an, ChinaPublication Year:2024Start Page:305-308DOI Link:10.1109/ICEICT61637.2024.10670916數(shù)據(jù)庫ID（收錄號(hào)）:20244117164503 -

Title:Optical alignment technology for 1-meter accurate infrared magnetic system telescope
Author Full Names:Fu, Xing(1); Lei, Yu(1,2); Li, Hua(1); Kewei, E.(1); Wang, Peng(1); Liu, Junpeng(1); Shen, Yuliang(3); Wang, Dongguang(3)Source Title:Journal of Astronomical Telescopes, Instruments, and SystemsLanguage:EnglishDocument Type:Journal article (JA)Abstract:Accurate infrared magnetic system (AIMS) is a ground-based solar telescope with the effective aperture of 1 m. The system has complex optical path and contains multiple aspherical mirrors. Since some mirrors are anisotropic in space, parallel light undergoes complex spatial reflection after passing through the optical pupil. It is also required that part of the optical axis coincides with the mechanical rotation axis. The system is difficult to align. This article proposes two innovative alignment methods. First, a modularized alignment method is presented. Each module is individually assembled with optical reference reserved. System integration can be completed through optical reference of each module. Second, computer-aided alignment technology is adopted to achieve perfect wavefront. By perturbing the secondary mirror (M2), the influence of M2 position on the wavefront is measured and the mathematical relationship is obtained. Based on the measured wavefront data, the least squares method is used to calculate the M2 alignment and multiple adjustments have been made to M2. The final system wavefront has reached RMS=0.12 λ@632.8 nm. Through observations of stars and sunspots, it has been demonstrated that the optical system has good wavefront quality. The observed sunspot is clear with the penumbral and umbra discernible. The proposed method has been verified and provides an effective alignment solution for complex off-axis telescope with large aperture. ? 2024 Society of Photo-Optical Instrumentation Engineers (SPIE).Affiliations:(1) Xi'An Institute of Optics and Precision Mechanics, Xi'an, China; (2) University of Chinese Academy of Sciences, Beijing, China; (3) Chinese Academy of Sciences, National Astronomical Observatories, Beijing, ChinaPublication Year:2024Volume:10Issue:1Article Number:014004DOI Link:10.1117/1.JATIS.10.1.014004數(shù)據(jù)庫ID（收錄號(hào)）:20241515878917 -

Title:30× VIS-SWIR wideband zoom lens design (invited)
Author Full Names:Qu, Rui(1); Zhang, Hongwei(1); Guo, Huinan(1); Li, Jian(2)Source Title:Hongwai yu Jiguang Gongcheng/Infrared and Laser EngineeringLanguage:ChineseDocument Type:Journal article (JA)Abstract:Objective High function density electro-optical (EO) system is becoming an important development direction at present and in the near future. With the gradual maturity of wide-band infrared detector technology, VIS-SWIR (from visible to short wave infrared) wide-band confocal zoom optical system， which can support various operational modes such as color imaging, fog penetration, and low-light conditions, effectively simplify the overall design of EO systems, turns into an important mean to realize the high functional density and SWaP&C (Size, Weight, Power, and Cost) of EO system, but optical materials show great differences in dispersion characteristics within this band, which makes design of continuous zoom system difficult and time-consuming. Studying of the corresponding optical system design method become necessary and urgent. Methods In order to solve this problem, a wide band zoom optical design model (Eq. (1)-Eq. (3)) is established with the combination of classical continuous zoom system design model and the achromatic conditions in the design of wide-band optical system. The parameters affecting the color aberration distribution of the whole system are explicitly demonstrated in the model. Based on the proposed model, the methods of optical power distribution and material selection are further discussed. Considering the dispersion characteristics of glass materials in different bands, some material using guidelines with examples in Tab.1 of wideband zoom lens design is provided. The extraordinary applications of the cemented elements, especially the synthetic abnormal dispersion characteristics and its synthetic method, are pointed out explicitly. Results and Discussions A wideband (VIS-SWIR) optical system under the requirements of F≤5.5, focal length 10-300 mm, horizontal field of view 38.8°-1.25°, waveband of 0.48-1.7 μm, 1 080 P InGaAs detector with pixel size of 3.45 μm is designed (Fig.3) to fulfill multi-band imaging by switching filters, and realize the common aperture integration of different functions such as color/fog-penetrating/laser/low-light imaging through a switching mechanism or a dichroic prism (Fig.4-Fig.5). It can be observed from Tab.3 that at a frequency of 100 lp/mm and 145 lp/mm, the MTF values at the edge of the field of view are approximately 0.3 and 0.1 across the wide wavelength range of 0.48 μm to 1.7 μm, the relative distortion at each focal length position is less than 2%; the chromatic focus shift at each focal length position is within the focal depth (162 μm) as 1.1 μm is taken as the central wavelength. The zoom lens system, which uses 7 kinds of optical glass, consists of 18 lenses, total length 190 mm, has good image quality and tolerance character through the full zoom range. Conclusions Starting from the zoom system design model, a design method for a wide-band zoom system is discussed with consideration of the achromatic conditions within and between bands of a wide-band system. Material selection criteria for different components of the zoom system are provided, which reduces the time-consuming and tedious trial-and-error process of traditional methods. This approach can effectively guide the design and development of related optical systems. As an example, a continuous zoom optical system with a wide wavelength range of 0.48 μm to 1.7 μm is designed using only commonly used optical glass. This system achieves integration of a common aperture and common focal plane for the visible light, near-infrared, and short-wave infrared bands. It features a telephoto ratio better than 0.64 and a zoom ratio of 30×. Additionally, it demonstrates excellent imaging quality throughout the entire zoom range and is compatible with multi-band, multi-mode, and multi-purpose applications, making it promising for widespread use in related fields. ? 2024 Chinese Society of Astronautics.

Since each application normally requires a different set and number of spectral bands, the development of customized spectroscopy solutions with more compact size and lower cost becomes quite important. In this paper, we demonstrate a compact, highly customizable imaging spectrometer scheme based on custom-made multi-strip filter arrays, which maintains an average high transmission of ～85%, narrow bandwidth of ～30 nm, and high optical density of ～OD2 in the blocking regions across the visible to near-infrared waveband. Spectral imaging experiments are conducted, and the accurate reconstruction of sparse spectral image data is demonstrated as well to prove the validity of the proposed scheme. As a result, the work reported in this paper allows researchers to develop customized spectral imaging equipment in a relatively easy way and also has a great potential to be engineered further for scalable production with a quite low cost. ? 2024 Optica Publishing Group ? 2024 Optica Publishing Group (formerly OSA).
