像增强器荧光屏亮度均匀性是评价像增强器的重要指标，其测试是像增强器测试领域的重点与难点。本文介绍一套我们研制的像增强器荧光屏亮度均匀性自动测试系统，该系统使用图像采集与图像处理技术，做到了自动测试，并且使测量精度提高了一个数量级。文章首先介绍了像增强器荧光屏亮度均匀性定义与传统光学测试方法，然后从传统方法的缺陷入手，系统阐述了新系统的工作原理、系统构成、测量结果。文章的最后对新系统测试结果与目前常规使用的光学测量结果进行了比较，从而体现该系统的独特性与优越性。
Image intensifier screen brightness uniformity is an important indicator of image intensifier evaluation, the test is like the focus of intensifier testing and difficulties. This article introduces a set of automatic intensifier screen brightness uniformity testing system developed by us, which uses image acquisition and image processing technology to do automatic testing and improve the measurement accuracy by an order of magnitude. The article firstly introduces the definition of brightness uniformity of image intensifier screen and the traditional optical testing method. Then, starting with the defects of traditional methods, the working principle, system configuration and measurement results of the new system are expounded systematically. Finally, the article compares the results of the new system test with those of the conventional optical measurement to show the uniqueness and superiority of the system.
