微光像增强器在热带雨林中的环境适应性分析

Environmental Adaptability Analysis of Low-Light-Level Image Intensifier in Tropical Rainforest

针对微光像增强器在高湿、高热环境易产生失效和劣化现象的问题,对2种型号的微光像增强器进行比较分析。以热带雨林环境为试验背景进行棚下暴露试验,以试验前后微光像增强器的亮度增益、分辨力、等效背景照度、信噪比作为参考依据,并结合环境因素监测数据,分析微光像增强器在热带雨林中的环境适应性。通过两年的试验结果表明:A型微光像增强器在热带雨林自然环境中的适应性比B型微光像增强器稍好。该试验结果对微光像增强器的使用、维护、性能评价以及设计改进具有一定的指导意义。

Aiming at the problem that low-light-level image intensifier was easy failed and inferior in high temperature and humidity environment, 2 types of low-light-level image intensifier were comparatively analyzed. Took tropical rainforest environment as background to exposure test under shed, in order to luminance gain, resolution, equivalent background input, signal-to-noise ratio of front and behind of testing for the reference, linked dates of natural environmental factors, environmental adaptability of low-light-level image intensifier in the tropical rainforest was analyzed. Through 2 years of testing, the research results showed that environmental adaptability of A low-light-level image intensifier in the tropical rainforest was better than B low-light-level image intensifier. The test result has certain guiding significance to operation, maintenance, performance evaluation and design improvement of low-light-level image intensifier.
