The use of a computer-generated hologram (CGH) in interferometric testing provides new methods for highly accurate optical measurement. To fabricate a CGH, polygons are used to approximate the smooth CGH pattern. Because the data size supported by CGH wri

A novel long wavelength photodetector with dual-wavelength spectral response is designed and fabricated using a step-shaped Fabry-P′erot (F-P) filter structure. The step-shaped GaAs/AlGaAs distributed Bragg reflectors and the InP PIN photodetector are gro
非制冷红外探测器产生的杂散光会在焦平面形成非均匀的图像,而在探测器窗口附近使用光阑,并对其开孔形状进行优化设计,是抑制杂散光的关键。利用区域法建立了杂散光在焦平面上的照度分布计算模型,并建立了变量模型和目标函数模型,以区间穷举法作为极值搜寻方法,完成了优化光阑开孔的程序编制。针对某款存在杂散光问题的非制冷红外探测器,利用所提数学方法优化设计了光阑的开孔形状,极大地削弱了由杂散光引起的“锅盖效应”,从而验证了光阑开孔形状优化设计方法的正确性与实用性。
Limitations for tungsten as plasma facing material in the diverse scenarios of the European inertial

提出了一种基于光反馈的双波长光纤环形激光器有源传感的模型。通过光纤光栅对激光器的波长进行选择, 输出不同波长的两路光反馈信号, 实现光纤环形激光器的波分复用。根据光纤环形激光器的超越方程, 理论上得出系统的输出变化。系统的输出信号与自混合干涉有着相同的灵敏度, 同时可根据条纹的倾斜情况辨别物体的运动方向。系统中的激光器不仅作为传感光源, 同时也作为传感敏感元件, 实现光纤环形激光器的有源传感。模拟分析了两路不同波长信号之间的变化关系, 考虑外部靶面位移大小对系统输出的影响。实验观测的结果与模拟结果相一致。
The development of optical methods in modern medicine in the areas of diagnostics, therapy, and surgery has stimulated the investigation of optical properties of various biological tissues, since the efficacy of laser treatment depends on the photon propa
