摘　　要：在ＳＰＲＩＴＥ探测器的研制和生产检验中，对其调制传递函数（ ＭＴＦ） 进行测试，可以分析和评价探测器的空间分辨率。文中将线扩散函数法用于该方面的测试，描述了一般的光路安排和自动测试方案，而且考虑了测试用光学投影系统对探测器 ＭＴＦ 测试的影响，以及相应的测试、补偿方法。In the development or manufacturing quality control of SPRITE detectors, it is need to measure their modulation transfer function (\%MTF\%), which characterize the spatial resolution of the detectors. A scheme of SPRITE detector′s \%MTF\% measurement based on its line spread function (LSF) is described, including the generic optical arrangement and the scheme of auto\|measurement system. The method, which can eliminate the ill influence of the optical projector on the measurement, is also described. \;
