摘要: 本文对白光处理系统的主要噪声——输入面上的振幅型颗粒噪声进行了研究,从理论上分析了光栅编码片中振幅型噪声的形成原因。说明傅里叶频谱面的滤波处理及编码光栅的衍射效率对图象输出信噪比的影响。

Abstract: The amplitude film-grain noises are the important noises in white-light optical processing system. Their appearance gives a low output SNR. This is mainly influenced by the filtering process in Fourier plane and the low diffraction efficiency of the encoding grating.
