Removal of Multiple Images in Digital Holography and Improvement Effect by Image Processing

Abstract

Holography records the amplitude and phase of the light wave from the object to be recorded as interference fringes by interfering with the reference light. Then, it is a technology to reproduce the complex amplitude distribution of light waves by using the diffraction phenomenon. Computer-Generated Holograms (CGH) has made it easier to realize interference fringes. In holographic memory, the lens term is used for image multiplexing / demultiplexing, and research is being conducted to improve the deterioration of the reconstructed image by image processing. This paper evaluates the creation of CGH, image multiplexing / demultiplexing by lens terms, and noise removal by filters as digital technologies by simulation. In addition, the limit of the total number of page data is shown, the improvement of the reconstructed image by image processing is confirmed.
