True-color rainbow holography of 3D diffuse objects with synthesized slit

A new method with one wavelength laser for making 3D diffuse objects true color rainbow hologram on photoresist plate is presented. In this method, we have used the synthesized slit technology to record the true color rainbow hologram H2. It results in a higher energy utilization. Otherwise, it is also easy to control the color reproduction of the reconstructing image. About the advantages mean it is of value in fabricating 3D diffuse objects true color embossed rainbow hologram. A satisfactory experimental result is obtained and the theory analysis is given.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
