对于远距离、大视场、多个运动目标的光电跟踪,现有光学系统形式难以同时兼顾大口径、大视场与高角分辨率的要求。通过模仿人眼小凹转动视觉生理机制,设计了一种轻型物方扫描校正镜组,具有中红外成像与激光测距的共口径同轴五反式新型光学系统。该光学系统主镜口径为1000mm,瞬时扫描有效口径为600mm,最大视场角达到20.7°,中波红外成像传感器像元角分辨率优于13!rad,激光测距单元作用距离达到20km。该新型光学系统具有大视场范围,可同时对6个以上远距离高速运动目标进行跟踪。

A quasi-continuous-wave intracavity frequency-doubled Nd:YAG laser which operates at 660 nm is studied. By using a flat-flat laser cavity, 2 Kr-lamps, KTP crystal and an acousto-optically Q-switch, 2-W output power at 660 nm is obtained. The relationship
We present two novel 1*N dynamic optical couplers that are based on Dammann gratings to achieve dynamic optical coupled technology. One is presented by employing a specially designed Dammann grating that consists of the Dammann-grating area and the blank
We propose a general correction method for the efficiency measurement of optical components in the 45–110 nm range to eliminate the contamination of higher-order harmonics at beamline U27 of the Hefei Light Source (HLS). The influence of harmonics can be

本文首次提出一种散斑剪切相机.该相机能把曲率、扭率和斜率的二维信息同时记录在一张双曝光散斑图上.对散斑图进行滤波分析时在频谱面上出现十三块互不重叠的衍射晕.在适当的衍射晕上滤波即可获得二维曲率、扭率和斜率的等值全场条纹.
评述了亚亳米波段内波长固定的和波长可调谐的激光器的现状。波长固定的激光器包括放电泵浦气体激光器和光泵浦气体激光器。后一种激光器在亚亳米波段有1500多条激光谱线,并作了详细论述。概述了可调谐亚亳米波激光器和相干光源,它们是由半导体激光器、差频振荡器、光参量振荡器、产生边带的双光子混频和喇曼激光器。
