A wide beam collimating method with double LD modulation is introduced in thes paper.
本文介绍一种双半导体激光器（ＬＤ）交替调制宽光束准直方法。
Based on the new configuration of optic stress system, we need to design a wide bands and long focal night vision collimating lens.
依据新配置的光应力系统试验要求,需设计一套大视场、宽光谱、长焦距的微光准直物镜。
However, because of the work-band restrictions of the traditional LLL image intensifier test system, it s unable to test ultraviolet (UV) and near-infrared bands of the image intensifier; therefore it s necessary to develop a new test system to complete the wide spectrum of the image intensifier performance measurement.
传统的微光像增强器测试系统只能在可见与近红外范围工作,无法对紫外波段的像增强器进行测试,因此需要研制全新的测试系统来完成宽光谱像增强器的性能表征。
