Holograms of a 3D object synthesized at the receiving end of the communication channel in Dot Matrix technology

Abstract

The manuscript presents experimental results on the recording and restoration of 3D holographic frames suitable for transmitting 3D holographic images with the frame rate required for TV images and the resolution of the Full HD standard and higher. The method is based on the previously proposed technology for recording and transmitting a depth map and surface texture of the holographic object over the communication channel and digital synthesis of the hologram at the receiving end of the communication channel. The obtained result reduces the frequency band required for the transmission of 3D holographic information, similar to SSB technology, since the carrier spatial frequency of the hologram in this method is not transmitted through the communication channel, but is synthesized in the hologram already at its receiving end. Experimental results of hologram synthesis at the receiving end of the communication channel in DotMatrix technology are presented. The method considered in this manuscript is convenient for multiplexing 3D images, transferring them from one part of the electromagnetic spectrum to another, as well as for creating hyperspectral images. The work implements the technology of a holographic phototelegraph, which, when using high-speed dynamic holographic monitors, can solve the problems of creating 3D TV and augmented reality.
