用于微光夜视仪性能检测的夜间仿真环境

Night Simulation System for Low-Level-Light Night Vision Systems Testing

作为开拓人眼视觉的夜视技术,自20世纪30年代出现以来,已经取得了迅猛的发展和应用,尤其是研究低照度下实现正常观察的微光夜视仪,已相继研制成功了性能成熟的四代产品,并在工业、农业、国防建设等方面有着极为广泛的应用前景。其作用距离的检测一般都在野外进行,文章从实际景物和夜天光的辐射特性出发,介绍了在暗室中研制符合实际景物反射率、对比度的目标和场景以及符合光谱要求的均匀夜天光模拟器,从而为微光夜视仪性能的检测提供了一个稳定的夜间仿真环境。

Testing of the LLL night vision systems always happen at outside. According to the radiate characters of natural scenery and night sky light, an arrangements has been made to simulate a uniform night sky light as well as targets and spot scenes which conform to actual conditions of reflectivity and contrast within a darkened room, thus providing a steady night simulation system for testing LLL vision systems.
