1.一般介绍象增强器是电子光学器件。它可以用电子学方法增强聚焦在光电阴极上的景物图象。增强了的图象显示在荧光屏上。象增强器由光电阴极、电子光学透镜和荧光屏组成。现有两种类型的被动式象增强器: a)第一代被动式象增强器(单级和三级级联,均为倒象式); 1. General Introduction Image intensifiers are electronic optics. It can electronically enhance the scene image focused on the photocathode. The enhanced image is displayed on the screen. Elephant enhancer by the photocathode, electronic optical lens and screen composition. There are two types of passive image intensifiers available: a) the first generation of passive image intensifiers (single and triple cascade, both in inverted image);
