本文描述了用于中间弹道高速摄影荧光转换屏的设计特点、性能测试和实验结果。文中讨论了Ｇｄ２Ｏ２Ｓ：Ｔｂ和（Ｚｎ，Ｃｄ）Ｓ对Ｘ射线的吸收系数、发光效率以及荧光光谱与变象管Ｓ—２０阴极光谱灵敏度曲线相匹配的相关曲线；测试了转换屏的相对发光强度、分辨率及其余辉。实验证明本屏发光亮度比钨酸钙屏高６０倍左右，屏分辩率达５１ｐ／ｍｍ，余辉时间为８μｓ，多幅摄影结果证明第一幅的图象对第二幅照片无“拖尾”现象，本屏已达到了中间弹道高速摄影转换屏的实用水平。
This article describes the design features, performance tests, and experimental results for a fluorescence transition screen for intermediate ballistic high-speed photography. In this paper, the correlation curves of absorption coefficient, luminescence efficiency, and fluorescence spectrum of Gd2O2S: Tb and (Zn, Cd) S on X-rays and the sensitivity curve of fluorescent tube S-20 cathodic spectrum are discussed. The relative luminescence intensity , Resolution and afterglow. Experiments show that the screen brightness than calcium tungstate screen 60 times higher, screen resolution of 51p / mm, afterglow time of 8μs, a number of photographic results prove that the first picture of the second photo no “trailing” Phenomenon, this screen has reached the intermediate ballistic high-speed photography conversion screen practical level.
