Design method of resolution test system for portable low-level-light night-vision device
Keywords:
low-level-light night-vision viewer, methodAbstract
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. © 2022 Editorial office of Journal of Applied Optics.
