摘要

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。

Abstract: The low-level-light (LLL) night-vision viewer is a necessary device in night fighting of information warfare, which is widely used in the field of night-vision individual reconnaissance, gun sight as well as vehicle-mounted and airborne field. Resolution is an important parameter to evaluate the detection ability of LLL night-vision viewer, and also is the key indicator to reflect its comprehensive performance. In order to solve the difficult problems of LLL night-vision viewer in each link of the whole life cycle, such as field operation, maintenance and service, a portable LLL night-vision viewer resolution test system was developed, which was composed by light source components, battery, target wheel, objective lens, illuminometer, voltage measurement feedback module, adapter and touch screen, etc. The proposed test system realized the test of resolution for LLL night-vision viewer, and could replace the laboratory test system on site to make up for the defects such as large size and inconvenient to carry.
