Abstract
The paper 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 a resolution of the Full HD standard and higher. The Patent RF No. 2707582 proposed a method for compressing holographic information and transmitting it using a procedure similar to SSB over conventional communication channels. In this work, the holographic information of a 3D portrait of a person, transmitted and received via the Wi-Fi communication channel, was restored in the form of a rainbow hologram, as one of a variety of holograms, by the computer addition of the carrier spatial frequency, and then hologram was actually produced on a photoresist. This technology can be used to create a holographic phototelegraph or, if there is a dynamic holographic display, to create a holographic television and 3D augmented reality.
Highlights
The problems related to holographic TV infringe on the interests of experts both in the area of holography and in image coding
High requirements in terms of the amount of information processed in this manner and the processing rate are mentioned. This is due to the fact that each frame, which is a 3D array of the object holographing data, should change at a frame rate accepted by the major TV standards
The number of points on a hologram is inversely proportional to the size of the Airy spot, and for the focused image holograms, their number is inversely proportional by the order of magnitude to the wavelength
Summary
The problems related to holographic TV infringe on the interests of experts both in the area of holography and in image coding. The difference between the proposed method and the SSB is the fact that the side spatial frequencies are not transmitted, but are still created at the receiving end of the communication channel on the basis of the two transmitted image modes: depth map + surface texture of the 3D holographic object.
