Abstract
In recent years, the application of interference fringe type Computer-Generated Holography is expected to improve compression transmission technology. Existing modulation methods include phase shift keying for amplitude phase modulation and quadrature amplitude modulation. In this paper, 256 gradations of the input image data on the transmitting side are divided into a certain range, and the center value is obtained in each range. CGH was created from this data and transmitted in a compressed or uncompressed frequency division multiplexing system. Using a text file between transmission and reception, we made it an ideal transmission line that can round numbers to any number of digits after the decimal point. We propose a method for obtaining information based on the gradation of the reconstructed image of CGH. In order to use the proposed method for existing modulation methods, it is necessary to accurately transmit the gradation of the reconstructed image of CGH and faithfully reproduce the gradation before transmission as a prerequisite for communication quality. We have not found any data communication using the gradation of the reproduced image of interference fringe type CGH, or information compression in transmission using FDM of CGH. Therefore, it was examined by simulated transmission by simulation on a computer. In addition, the amount of information was compared with the 8-phase PSK of amplitude phase modulation. From these studies, we report that there is a possibility that it can be applied to data communication with a large amount of information.
