Transmission of 3D Holographic Information via Conventional Communication Channels and the Possibility of Multiplexing in the Implementation of 3D Hyperspectral Images

Abstract

This paper shows the possibility of transmitting 3D holographic information in real time with a TV frame rate over conventional radio channels by transmitting two two-dimensional signals in two image modes: depth map and surface texture of the object (mask + texture). The authors point out that it is similar to compression through eliminating the carrier and it is inherently similar to SSB (single-sideband modulation) but has higher resolution ability in reconstructing 3D images. It is also shown that such technology for transmitting 3D holographic information is in good agreement with the tasks of both aggregating and multiplexing 3D images when they are transferred from one part of the electromagnetic spectrum of radiation to another and the creation of hyperspectral 3D images.

Structured Light Patterns Work Like a Hologram

“…The possibility of efficient compression of holographic information, similar to the transmission at one sideband known in radio electronics, was demonstrated in patent RU 2707582 C1 [7]. In this situation, as shown in [14], this compression is already sufficient for the transmission of 3D holographic information along the radio communication channel. It is even more so if, as described above, the transmission of one of the two components of 3D image basic modalities (depth maps of the holographed 3D object) is replaced by the structured light pattern formed by photo capture of the lateral projection of straight fringes on the 3D object.…”

“…The multiplier standing at the cosine is the visibility (V) of the interference structure of the hologram. The carrier spatial frequency formed in (1) of plane waves that are permanent over the (x 1 , y 1 ) space in the simple case is proportional to the derivative of ϕ o with respect to the coordinate, while its deviation, containing the information on the holographic object [14], is proportional to the derivative of ϕ r depending on the wavelength λ, which allows one to separate diffraction orders in the restoration plane (x 1 , y 1 ), while d x,y max and d x,y min are their deviations.…”

“…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.…”

A Survey on Semantic Communications for Intelligent Wireless Networks

“…2. Holographic Communication will involve the transmission and reception of 3D holograms of human or physical objects [99]. Depending on the high resolution, wearables, and AI/ML, user equipment will render the 3D holograms for displaying the remote users or machines local presence, to create increased realistic local presence of a remote human or object.…”

3D optical illusion as visualisation tools in spatial planning and development

“…Therefore, in the common understanding of holography is best known as a method of generating three-dimensional images. Both hologram technique and 3D optical illusion (commonly known as a hologram) are applied inter alia in education 51 – 54 ; medicine 55 – 58 , biotechnological sciences and industry 59 – 61 , marketing 62 – 65 , microscopy 66 , 67 , protection equipment 68 , 69 , and holographic cinema, television 70 .…”
