“…In the general case, the interference structure of the hologram is more complicated, because both in the carrier spatial frequency and in its deviation, the variable over the coordinates V(x 1 , y 1 ) makes its own contribution to spatial harmonics, so it is better to study them by means of numerical modeling [14][15][16]. The classical approach to the digital synthesis of a hologram is in the computer modeling of the process according to Figure 1.…”

The subject of this investigation is light diffraction from a structure formed at the lateral projection of structured light on the surface of a 3D object. It is demonstrated that the patterns of vertically structured light fringes change their structure during the lateral illumination of a 3D object, and take on the properties of holograms. The diffraction of light from this structure forms several diffraction orders, and one of them can restore the image of the 3D object. Results of the numerical experiment demonstrating the possibility to restore 3D holographic images by these patterns at a wavelength corresponding to Bragg conditions are presented. The obtained result allows an order of magnitude higher compression of the holographic information about a 3D object to be transmitted along the communication channel, in a volume that is sufficient for visual perception, and for the observation of both the horizontal and vertical continuous parallax. Results of the experiments on the transmission of this compressed information are presented to demonstrate that the TV frame rate frequency of the 3D holographic video sequence is quite achievable.

When holographic information is transmitted through communication channels, a problem arises associated with the large capacity of holograms. In the patent of the Russian Federation No. 2707582, the possibility of compressing holographic information was shown, similar to the transmission on one sideband known in radio electronics. The experimental transmission of such compressed information over a Wi-Fi wireless communication channel with a frame rate of more than 25 frames per second is shown in this paper. The experiment of transmitting holographic information of 3D images over a wireless Wi-Fi communication channel to simulate 3D video using the FTP protocol was carried out. In accordance with the RF patent No. 2707582, each transmitted frame of a 3D image was the sum of two 2D frames-a texture (2000x2000 pixels) and a mask (1000x1000 pixels). To simulate the transmission of a video sequence, packets of 500 double frames were transmitted simultaneously. The transmission times of these frame packets measured in real time by FileZilla showed that the transmission of full holographic information about a 3D object in real time with a frame rate greater than 25 frames / sec. quite feasible.
