A system was set up to test the modulation transfer function (MTF) of a photoelectric simulation system. The method used the ratio of magnitude of the output image to the input image.

建立了某光电仿真系统的调制传递函数(MTF)评测系统，系统采用频谱对比法测试了仿真系统的MTF。

To verify the accuracy of this method, the results are compared with the MTF values obtained by the original method, in which the gray level of the test chart pictures are read and calculated.

将这种方法所测量的结果与实际读取胶片时由分辨率板的图案中黑白条纹灰度值计算出的MTF值进行了比较，验证了这种方法的准确性。
