用于微光夜视仪性能检测的夜间仿真环境

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.

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

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.
