Research And Development Of Luminance Gain And Equivalent Background Input Test Set For LLL Image Intensifier

Luminance gain and equivalent background input are two important factors for evaluating the performance of image intensifier. Based on the requirement of the measurement of these two factors, the article describes the measuring principle and structure design of luminance gain and equivalent background input test set for LLL Image Intensifier. W ith the new developed machine. various types of image intensifier were measured of its lightness and effect—equalized background. The measuring results were provided and analyzed. The results show that the structure design of the measuring machine is qualified.
