Design method of resolution test system for portable low-level-light night-vision device

  • 摘要: 微光夜视仪是信息化战争夜战中必备的一种仪器,广泛应用于夜视单兵侦察、枪瞄、车载、机载等作战领域。分辨力是衡量微光夜视仪探测能力的重要参数,是反映其综合性能的关键指标之一。为了解决现场使用、保养和维修等全寿命周期的各个环节中微光夜视仪的性能保障难题,研制了便携式微光夜视仪分辨力测试系统,主要组成部分包括光源组件、供电电池、靶标转轮、成像物镜、照度计、电池电压测量反馈模块、适配器和触摸显示屏等,实现了对微光夜视仪分辨力的测试,可在现场替代实验室测试系统,弥补其体积大、不便携带等缺陷。
