Abstract


Optics wavelets transform is a real time digital process method which has developed in recent years. It can provide not only the means to suppress noises and extrude information, but also an effective approach to realize multi-distinguishing rate image process. If it would be applied in image and data compressing field, there will be a capacious applying prospect. This article systematically describes the basic principles and characters of wavelets transform, and expounds two means of realizing optics wavelets: space-field method, and frequency-field method. And the article analyses 4f optics system’s application of optics realizing of optics wavelets, discusses the election of optics filter and the confirmations of parameters’ targets, and brings forward firstly an error analyzing method in the course of realizing wavelets transform by 4f optics system and the improving orientation in the future.
