%X Concerning the low pass characteristic and white Gaussian noise of the typical information optics system, by introducing the statistic parameters from synthetic aperture radar (SAR) research, a new wavelet threshold denoising method was provided. Reality and emulational experiments show that the method can effectively denoise the image and keep useful detail information. It is suitable for the applications of low pass filtering and white Gaussian noised system like 4f system.
