Experimental Studies of the Method Producing Computer-Generated Fourier Microholograms in the Holographic Memory Optical System of Projection Type

The article presents the results of experimental studies of the projection system recording computer-generated Fourier microholograms on photosensitive media as well as the information recovery system. Task-orientated prototypes implementing the projection method of generating holographic medium and reading the information registered in it are developed. The parameter optimization technique for both the Fourier microholograms of a digital generation channel and the projection optical recording channel of the holographic memory system is provided. The results of the system experimental study that confirm the high quality of the recorded holograms are presented. The conducted experiments also confirm the possibility of increasing the information density on a photosensitive medium by using the multiplexed recording microholograms.
