Research on Digitally Integrated Test System for Performance Evaluation of Image Intensifier and Intensified CCD

摘要

Image intensifier and intensified CCD (ICCD) are critical components in the field of night vision technology. There are some specifications, such as luminance uniformity, fixed pattern noise, resolution, modulation transfer function (MTF), etc., which can be used to evaluate the performance of such components. A digitally integrated test system for performance evaluation of image intensifier and ICCD is described in this paper. The system can test 11 specifications for imaging intensifier (generation 1, 2 and 3) and ICCD with some essential accessories. The system operation theory, structure and testing results are represented in detail. The system has been run at North Night Vision Technology Co. for about 10 months. The results after long running period are given. And the factors that affect the measurement accuracy are analyzed. The results show that the digitally integral system has high measurement precision and stability.
