Features of the Use of Volumetric Fourier Holograms in Radio Communication Equipment Placed on Vehicles

Abstract

AbstractThe equipment of radio channels, built using elements of radio photonics, has a higher speed, a larger dynamic range, both in frequency and in terms of the level of the information signal, reduced power consumption and noise level, the possibility of varying the parameters and characteristics of signals in a wide dynamic range of values. A possible direction for improving the technical characteristics of radio photonics devices is the construction of these devices using volumetric Fourier holograms in their design. Informative parameters of the light flux in holographic radio photonic devices are the intensity, frequency and phase of this light flux. The values ​​of the frequency and phase of the modulated light flux, as well as changes in their values, can be recorded only as a result of measuring and analyzing the parameters of the interferogram formed in the radio photonic device. The maximum sensitivity and accuracy of interferometric measurements are observed in the formation and use of holographic interferograms in radio photonics devices. Volumetric Fourier holograms can be used as holograms in the design of such devices. The article reviews the physical properties of volumetric Fourier holograms, which determine the features of the construction of radio photonics devices using these holograms. An analysis is made of the features of volumetric Fourier holograms, which determine the relevance of their use in radio communication equipment. A reasonable conclusion is made about the possibility and prospects of developing and using holographic radio-photonic devices, including for their use in radio communication equipment placed on vehicles.KeywordsTransportRadio communication equipmentRadio photonicsVolumetric Fourier hologramPhysical propertiesFeature analysis
