Design and realization of low light level night vision device detection system based on machine vision

A detection system of low light level night vision device was designed and developed,which utilized the CCD component as the detection receiver of the output image.It can be used to test the image intensifier in low light level night vision system. The testing parameters of image intensifier performence in low light level night vision system were introduced, the comprehensive test method and principle for all the parameters were analyzed. Through the optimizing design of the architectural structure,optical system,CCD selection and testing software , it was realized that many performance parameters of image intensifier in low light level night vision system such as resolution ratio,brightness gain,brightness uniformity,brightness stability could be measured by single equipment. The experiments results show that the random measurement error is less than 3%.
