Luminance gain is an important parameter for predicting the life of low-light-level image intensifier. Highly accurate luminance gain measurements improve the accuracy of the low-light-level image intensifier life prediction. This article is based on the measurement principle of luminance gain. By analyzing the components of the measuring device and the associated error characteristics, a treatment scheme that can effectively reduce the measurement error of luminance gain is given. The program has been experimentally verified to improve the accuracy of image intensifier life prediction. The relative deviation from the test results is less than 4%. An effective detection method to improve the engineering development efficiency of the low-light-level image intensifiers is presented.
