Paper Abstract

In this paper, a new storage approach of color films by means of a single-wavelength laser and SLMs is presented. A color film is illuminated with a beam of incoherent white light but filtered into red one. Then a frame on the film is imaged on a CdS liquid crystal SLM. The red coherent light of a He-Ne laser projects on the SLM as a reading light. So the output light of the SLM is also a red coherent light that carries the image information of the red incoherent light. By replacing filters with green and blue ones, three images of red coherent light can be produced step by step. A rainbow holographic recording geometry is arranged to store the three coherent light waves. Therefore, an image frame of the color film is stored in a rainbow hologram which can be preserved forever.
