Model for the brightness uniformity of fluorescence screen of image intensifier

The three elements of photoelectrical cathode, microchannel plate and fluorescence screen are important parts to imaging quality of low light and ultraviolet Image intensifier. To do research and analysis work on the Fluorescence screen parameter testing have practical significance to the understanding of the performance of fluorescence screen and then can help to know where improvement should be made and then achieve a best performance entire tube, This article mainly introduce the testing theory of the brightness uniformity of fluorescence screen of Image Intensifier and how to build a mathematic model.
