大光斑激光眩目光学系统设计

Design of Large Spot Laser Glare Optical System

针对目前全球严峻的反恐局势和大规模群体性事件的日益激增,设计一种非致命、非永久性致盲的大光斑眩目系统显得尤为重要。人眼对532 nm的波长较为敏感,因此系统选择532 nm波长的光束作为辐照光源,通过微透镜阵列和变焦系统分别对光束进行匀化和变焦扩束。利用光学设计软件Zemax对系统进行设计优化,并使用LightTools软件对系统质量进行评价分析。结果表明,大光斑激光眩目光学系统作用距离范围可达25~1000 m,光斑均匀度约为53%,作用面积为10×10 m^(2)。该技术成果在应对恐怖活动和大规模群体性事件中具有一定的应用意义。

In view of the current global severe counter-terrorism situation and the increasing number of large-scale mass incidents,i t is particularly important to design a non-lethal,non-permanent blinding large spot glare system.The human eye is sensitive to the wavelength of 532 nm,so the system selects the beam with the wavelength of 532 nm as the irradiation light source,and homogenizes and zooms the beam expansion through the microlens array and zoom system,respectively.The optical design software ZEMAX was used to optimize the system design,and the system quality was evaluated and analyzed by LightTools software.The results show that the distance range of the large spot laser glare optical system can reach 25~1000 m,the uniformity of the spot is about 53%,and the area of action is 10×10 m^(2).This technical achievement has certain application significance in responding to terrorist activities and large-scale mass incidents.
