In this paper, the information compressed and transmitted and reconstructed system (ICTRS) of CGH has been established. JPEG baseline image processing sytem and the image reconstruction system of Fresnel transform technique have been adapted. The information of processed CGH has been analyzed and to compare the information distribution of processed CGH with the original CGH. At last the noise affect of processed CGH in ICTRS has also been analyzed. And this CGH processed method has been verified with experiments.
