摘要
针对目前激光主动探测技术对军队光电装备造成的探测威胁,在不改变光电装备光学结构以及有限牺牲光电装备光学性能的前提下,实现其猫眼光学窗口的“隐身”。首先,基于磁致旋光晶体的法拉第效应,设计了加载于光电装备光学窗口前端的隐身装置。然后通过数值仿真和实验方法,从磁光晶体的性能、隐身装置消光比、隐身装置对像质的影响三个方面对该设计的可行性进行了分析。仿真及其实验结果表明:当磁光晶体能实现良好的消光效果,且加装隐身装置的光学窗口对像质影响很小。基于磁致旋光效应的隐身设计能够满足战场环境对军用装备的性能要求,且其消光比和对像质的影响程度能使光电装备在不影响正常工作的前提下有效实现隐身。
Abstract
To lessen the threat of being detected by laser active detecting system, a stealth method is put forward for the “cat′s eye” optical windows of the photo-electric equipments without changing their optical structure and decreasing their optical performance. Firstly, based on the magneto-optical rotation effect, the stealth device attached in front of the optical window of photo-electric equipment is proposed. Secondly, the feasibility of the design is analyzed by numerical simulation and experiment method in three respects:performance of the magneto-optical crystal, extinction ratio of the stealth device and the influence of the stealth device on image quality. Simulation and experimental results indicate that extinction ratio is satisfactory and the stealth device in front of the optical window has no influence on image quality. The device can satisfy the performance requirement for military equipments in a battlefield environment with the realization of stealth, a small extinction ratio and the maintenance of image quality.
