Abstract
A method for the formation and transmission of 3D holographic images is proposed, based on the formation of a 2D holographic signal by subtracting the carrier spatial frequency from the signal, thereby, compressing the holographic information for the purpose of fast transmission over a standard radio channel in real time. The information about the3D structure of the holographic object is recorded with the use of coherent and incoherent radiation, in which an analog of the object's hologram is obtained by structured light methods, suitable for transmission to a distance in the form of a 2D frame equivalent to a hologram with eliminated redundancy. This way of transmission of 3D holographic information is similar to the transmission known in radio engineering on one sideband with subtraction of the carrier frequency and the possibility of subsequent introduction of this frequency or any other carrier frequency at a distance from the holographic object. This method of transmission of 3D holographic information is applicable for problems of holographic TV and 3D augmented reality. Examples of the implementation of this technology in creating holographic images of a real 3D portrait of a person and transmitting it over WiFi are given. 3D images synthesized in the IR range are shown. This technology is easily adaptable to the tasks of integrating images of different parts of the spectrum of electromagnetic radiation. Possible applications of the method in 3D instrumentation are proposed.
