    Abstract:To evaluate the ability of space optical systems to suppress off-axis stray light, this paper proposes a stray light testing method for large-field of view, multispectral spatial optical systems based on point source transmittance (PST). And a stray light testing platform was developed using a high-brightness simulated light source, large-aperture off-axis reflective collimator, high-precision positioning mechanism and a double column tank to evaluate the stray light PST index of spatial optical system. On the basis of theoretical analyses, a set of calibration lenses and stray light elimination structures such as hoods, baffle and stop are designed for the accuracy calibration of stray light testing systems. The theoretical PST values of the calibration lens at different off-axis angles are analyzed by Trace Pro software simulation and compared with the measured values to calibrate the accuracy of the system. The testing results show that the PST measurement range of the system reaches 10-3 ~10-10 when the off-axis angles of the calibration lens are in the range of ±5? ~ ±60?. The stray light test system has the advantages of wide working band, high automation and large dynamic range, and its test results can be used in the correction of lens hood and other applications. ? 2013 IEEE.

    Abstract:Fluorescence lifetime of phosphors is a critical index in the field of high energy physics and astrophysical detection. A series of ZnSxO1-x:0.05Ce3+ phosphors with tunable short fluorescence lifetime were prepared by performing high temperature solid state reaction method. The phosphors exhibited two mixed phases consisting of the hexagonal phase ZnO and the hexagonal phase ZnS. They are spherical and the average particle size is 2.24 μm. As the component content of the ZnS in ZnSxO1-x:0.05Ce3+ phosphors varies, the emission wavelength can be tuned from 448 nm to 495 nm, the short fluorescence lifetime can be tuned within the range of 6 μs–200 μs. By performing exponential fitting, we obtained the equation for the variation of fluorescence lifetime of ZnSxO1-x:0.05Ce3+ phosphors with ZnS fraction. ? 2023 Elsevier B.V.

    Abstract:In this study, black silicon was achieved by femtosecond laser ablation of the silicon wafer surface. Surface microstructures of black silicon were closely related to laser ablation parameters such as energy density. Changing laser energy density could significantly alter the shape of microstructures including the base radius (r) and height (?) of the parabolic cone. The relationship between the base r, ? and the reflection, transmission, and absorptance of black silicon in the range of 260 nm to 1460 nm was simulated using the finite-difference time-domain method (FDTD). The results indicated that ? was directly proportional to the absorptance, while r presented an inverse proportion to the absorptance. And cot (Formula presented) (where θ represents the top angle of the microstructure) demonstrated a direct proportionality to the average absorptance. With different laser energy density the characterization was performed on the surface morphology parameters, absorptance, and photoelectric response efficiency of black silicon. The results showed that the change in absorptance was positively correlated with cot (Formula presented), but the correlation between photoresponse efficiency and cot (Formula presented) was not obvious. Raman spectroscopy characterization revealed a positive correlation between the peak intensity change at the Si-I (520 cm―1) and the photoelectric response efficiency. And the peak intensity at Si-I (520 cm―1) decreased with increasing laser energy density, indicating the introduction of more lattice defects, which weakened the efficiency of charge carrier transport. This study revealed the influence mechanism on the absorptance and energy density of black silicon with small changes of microstructure, which can provide a valuable reference for further optimization of the energy density of black silicon. ? 2024, The Authors.

    Abstract:Due to the strong reflective properties of the spacecraft surface coatings, there are significant challenges in processing images from outer space. Furthermore, the volume of data for image feature processing and matching is immense, and existing algorithms are insufficient for aerospace system applications. Therefore, this paper proposes a three-dimensional pose measurement algorithm based on binocular vision. The binocular vision-based three-dimensional pose measurement system consists of four main components: camera calibration, camera rectification, stereo matching, and pose determination. Traditional image processing algorithms are employed for satellite image processing. Camera calibration is performed using M software, and the calibration results are further optimized. Due to real-time requirements, an improved SIFT algorithm is used to detect local features in the images, extract feature points, and perform feature point matching under epipolar constraints. Experimental results demonstrate that this algorithm can achieve accurate and fast three-dimensional pose measurement. ? 2024 SPIE.

    Abstract:The oceans have a large amount of unexplored resources,so the exploration area of human beings is moving towards the unknown ocean as land resources are getting scarce. Underwater wireless optical communication technology with higher rates and better security has become the key to underwater environmental monitoring,wireless sensor networks,offshore exploration and communication between submarines. Vortex beams are a class of beams with helical phase wavefront carrying Orbital Angular Momentum(OAM),which have been widely used in the fields of optical communication,remote sensing and super-resolution imaging due to their specific helical phase structure and dark hollow ring light intensity distribution. The transmission of vortex beams in seawater environments is interfered by ocean turbulence,which results in light intensity scintillation,phase undulation and spot drift,which can degrade the communication quality. However,as human activities extend from free space to the marine environment,the demand for the communication capacity of underwater optical communication systems is increasing,so it is of great significance to study the coded communication of underwater vortex beams and their superposition states,and to further explore methods to suppress the effect of ocean turbulence on the transmission of the beams,for the underwater vortex optical communication systems. In this paper,power spectrum inversion method are used to establish a phase screen model of ocean turbulence,simulate real ocean turbulence,and study the light intensity and phase characteristics of Double Laguerre-Gaussian Vortex Beam (DLGVB) generated by coaxial superposition during transmission in ocean turbulence. The scintillation index of DLVGB beam under different ocean turbulence parameters and topological charge difference is simulated and analyzed. According to the scintillation index,the bit error rate of the underwater optical communication system based on On-off Keying(OOK)modulation under different ocean turbulence parameters is further calculated, and the bit error rate of the optical communication system under different topological charge difference is simulated and analyzed. The results show that the scintillation index of Double Laguerre-Gaussian Vortex Beam(DLGVB)increases with the decrease of turbulent kinetic energy dissipation rate,the increase of transmission distance,salinity temperature fluctuation equilibrium parameter and temperature variance dissipation rate. The main reason is that the intensity of ocean turbulence will gradually increase with the decrease of turbulent kinetic energy dissipation rate and the increase of salinity temperature fluctuation equilibrium parameter and temperature variance dissipation rate. Compared with the traditional Laguerre Gaussian vortex beam,the DLGVB beam with lower topological charge difference(v ? 2024 Chinese Optical Society. All rights reserved.

    Abstract:Infrared soft glass hollow-core anti-resonant fibers (HC-ARF) with low loss, excellent mode purity, and robust high-power transmission capabilities have vast potential in mid-infrared high-power laser transmission and biomedical fields. Despite this, the fabrication of these fibers still faces formidable challenges, coupled with an incomplete understanding of the transmission characteristics, thereby amplifying the value of further exploration. In this paper, we fabricate a six-cell nodeless infrared HC-ARF originating from purified sulfide glass, synthesized using a meticulous "stack-and-draw" method and dual-gas-path pressure control method. Notably, we experimentally validate the theoretical performance expectations of this fiber. The fiber exhibits outstanding transmission capabilities and optical transmission quality, characterized by a recorded loss of 0.56 dB/m at 4.79 μm. This is already comparable to traditional step-index sulfide fibers, fully demonstrating its tremendous research value and application potential. Our work has successfully fabricated the lowest loss anti-resonant fiber on record in the mid-infrared field, propelling the development of sulfide HC-ARFs into a new phase and laying a solid foundation for the realization of fiber applications in laser transmission and the biomedical field. ? 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

    Abstract:As one of the most promising schemes to address the bottleneck confronted by conventional optical devices (e.g., bulky sizes, high cost, and complex geometrical structure), metalens have drawn great attentions in the recent years. In this work, a metalens operating in mid-wave infrared (MW-IR) range is proposed, which can accomplish broadband achromatic under both x- and y-polarization incidence. In order to satisfy the strict phase requirements with relatively high transmission, three types of architectures composed of silicon symmetrical structures on a hexagonal magnesium fluoride substrate are delicately designed. In specific, these meta-atoms are supposed to simultaneously realize MW-IR waves focusing at 4.2 μm, and they can also compensate the phase differences between 3.7 to 4.2 μm. The numerical results indicate that the chromatic aberration in the concerned wavelength range can be well corrected for both x- and y-polarized incidence, and the corresponding maximum deviation values of focal length are only 3.10% and 3.09%, respectively. Moreover, the average focusing efficiencies of two different incidences are 51.15% and 49.01%, respectively. This work may have great potential to promote the integration of broadband MW-IR devices. ? COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only.

    Abstract:Mural paintings hold significant historical information and possess substantial artistic and cultural value.However, murals are inevitably damaged by natural environmental factors such as wind and sunlight, as well as by human activities. For this reason, the study of damaged areas is crucial formural restoration. These damaged regions differ significantly from undamaged areas and can be considered abnormal targets. Traditional manual visual processing lacks strong characterization capabilities and is prone to omissions and false detections. Hyperspectral imaging can reflect the material properties more effectively than visual characterization methods. Thus, this study employs hyperspectral imaging to obtain mural information and proposes a mural anomaly detection algorithm based on a hyperspectral multi-scale residual attention network (HM-MRANet). The innovations of this paper include: (1) Constructing mural painting hyperspectral datasets. (2) Proposing a multi-scale residual spectral-spatial feature extraction module based on a 3D CNN (Convolutional Neural Networks) network to better capture multiscale information and improve performance on small-sample hyperspectral datasets. (3) Proposing the Enhanced Residual Attention Module (ERAM) to address the feature redundancy problem, enhance the network's feature discrimination ability, and further improve abnormal area detection accuracy. The experimental results show that theAUC(AreaUnderCurve), Specificity, andAccuracy of this paper's algorithmreach 85.42%, 88.84%, and 87.65%, respectively, on this dataset. These results represent improvements of 3.07%, 1.11% and 2.68% compared to the SSRN algorithm, demonstrating the effectiveness of this method for mural anomaly detection. ? 2024 The Authors.

    Abstract:Photothermal superhydrophobic surfaces have been demonstrated for anti-icing/deicing applications. However, preparing these materials using simple and environmentally friendly methods remains a challenge. Herein, a high-efficiency energy utilization strategy based on a photothermal-wind synergistic effect combined with superhydrophobicity has been proposed for anti-icing/deicing. Using one-step femtosecond laser direct writing technology, we modified a polyether ether ketone surface, which resulted in a superhydrophobic surface with photothermal effects. The optimized fabrication condition was laser treatment with velocity of 80 mm s?1 (LT-V80), which gave a surface possessing a high water contact angle (~160.9°) and a low rolling angle (~3°), and excellent self-cleaning properties were seen. Furthermore, LT-V80 showed high light absorptivity (~94.6%), which caused the surface temperature to increase by 44.5 °C under 1.0 sun illumination. The addition of wind to the system resulted in a synergistic effect together with the photothermal and superhydrophobic properties, and caused a 87.1% reduction of the deicing time and a 220.3% increase in the icing time. This strategy also demonstrated good deicing efficiency in a cold outdoor environment. An efficient solar energy utilization strategy as demonstrated by LT-V80 indicates that efficient anti-icing/deicing is possible using simple, environmentally friendly, and low cost fabrication methods. ? 2025 The Royal Society of Chemistry.

    Abstract:There is a growing need for the lightweight acquisition, tracking, and pointing (APT) system during satellite launches due to the escalating demand in space missions. The APT system may work under multiple loading cases during different launch steps. Hence, this study introduces an innovative amalgamation of genetic operation and bi-directional evolutionary structural optimization (BESO) to fulfill the multi-objective requirements through the attainment of Pareto optimal fronts. A typical instance in two dimensions illustrates the effectiveness of the innovative multi-objective approach by contrasting the outcomes acquired from a solitary fulfillment requirement under two distinct burdens. Furthermore, the novel multi-objective method is utilized to remove inefficient material from the APT system by 20.12%. To ensure the safety of the lightweight design, the simulation and experiment of random vibration are both investigated according to the fundamental natural frequency of the launcher. ? 2024 World Scientific Publishing Company.

    Abstract:The hollow core anti-resonant fibers (HC-ARFs) based on soft glass are in high demand for 3-6 μm laser delivery. A HC-ARF based on tellurite glass with 6 touching capillaries as cladding was designed and fabricated for the first time, to the best of our knowledge. A relatively low loss of 3.75 dB/m at 4.45 μm was realized in it. The effects of capillary number, core diameter, wall thickness of capillary, and material absorption loss on the loss of the HC-ARF were analyzed by the numerically simulation. The output beam quality was measured and the influence of bending on the fiber loss was discussed. The results of numerical simulation suggested that the theoretical loss of the prepared fiber can be reduced to 0.1 dB/m, indicating that tellurite HC-ARFs have great potential for mid-infrared laser applications. ? 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.
