【Abstract】 Noisy images with a periodic structure can be cleared by utilizing optical periodic average method. In this paper the higher signal-to-noise ratio obtained by this processing method was discussed, the experimental apparatus was improved, the specific pattern of filter used in the coherent optical system and the experimental results were given.更多还原
