报道了一种针对X 射线转换晶体光学性能综合测试的光电检测方法。从效能角度对测试装置进行优化，对系统固有的工频干扰与尖峰脉冲噪声采取了有效抑制措施。利用该装置测试了山西长城微光器材股份有限公司研制的某未知闪烁晶体的可见光光谱响应、光学转换效率、空间分辨率等性能。研究的光电综合测试方法为闪烁晶体材料的研制提供了一种性能测试借鉴。

A photoelectrical test method and the system are developed for messuring the optical performances of some scintillation crystals. The theoretical critical focal length of the measurement system is deduced and used in order to make the most of both X-ray photons and the effective area of the scintillation crystal panel. Furthermore, coaxial cable ordered is used to replace the carried wire to remove power noise. Experiments are successfully done to integrally test the spectral response, conversion efficiency and spatial resolution of some scintillators made by Shanxi Changcheng Microlight Equipment Co. Ltd. and the results show that the presented system is helpful to test the scintillator properties.
