Abstract
In night vision technology, due to the passive technology's unidirectional and high concealment advantages, it has been paid attention to, among which the low light level night vision instrument has obtained rapid development. With the improvement of the performance of low light level night vision instrument, it is very important to test the index of high resolution and wide field of view to ensure the comprehensive performance of night vision instrument. In China, in the development of low-light night vision instrument, many standard equipment in the laboratory are used to piece together, or the equipment developed is a general low-light test equipment, and a special and standard low-light night vision instrument tester has not been developed. In this study, a comprehensive measurement method of night vision is proposed. Through the design of resolution, contrast test module, field of view Angle test module and data acquisition system, a complete and multi-functional test system is formed, in which the system aperture is greater than 110mm, the resolution test range is 0.06~2.6mrad, and the field of view Angle measurement range is ±25°. The light source brightness ranges from 1.6×10-5 to 5×10-3 cd/cm2. Through the docking verification with the night vision instrument, the low light level night vision instrument tester has realized the accurate measurement of the low light level night vision instrument's resolution, field Angle, contrast and other indicators, which provides a guarantee for the performance of the low light level night vision instrument.
