Abstract

The article discusses the possibilities of using holography for parallel transmission of information in communication channels. Existing channels use serial transmission. At the same time, there is an effect that can be considered as a parallel transmission of information – holography. To transmit a hologram over a communication channel, it is necessary to transpose the space-time matrix. In this case, the information is deployed in space, and two local points are used in time – the moment of the formation of the object and the moment of the formation of the hologram. One option is optical holography, where an array of lasers pointed at the receiver matrix forms an interference pattern on it. The second option is the use of radio holography, the third is the transfer of the communication channel from the space-time domain to the time-frequency domain. To do this, one can use the transfer of the information block into a linear array of the spectrum in the frequency domain (time-frequency transposition). In this case, the hologram is aligned in the frequency space – the shape of the hologram corresponding to the transmitted information block contains the signal spectrum. The approaches considered are a problem statement for developing methods for parallel holographic transmission and creating communication channels that practically do not have an upper bandwidth limit. The theoretical limit is the transmission rate of a hologram – the amount of information contained in a three-dimensional image of a complex object, within the duration of one period of an electromagnetic wave.
