The advantages and disadvantages of differents rainbow holographys and the improvements made on them
 
Abstract:In this papers,the author first simply gived a description of the origin of the holograpy and the principle of the rainbow holography.Second,he elaborate the principle as well as the advantages and disadvantages of two found methods that about the made of the rainbow holography.Further more,he summed up the developments and the improvements which were made upon the founds of the two methods through intergrating many documents.
