Subject of study. The possibility of real-time transmission of holographic information using standard radio channels by its compression through the removal of the carrier frequency and the use of a single sideband is investigated. Main results. We demonstrate that, according to Russian patent 2,707,582, information about a three-dimensional (3D) object can be stored in the form of two two-dimensional frames, one of which is the texture of the object surface, whereas the other is the depth map of its surface. After considering two principal methods for the formation of such a depth map, namely, the time-of-flight method and the method of structured light, we selected the latter owing to several advantages. This method was used to simulate the real-time recording process of a 3D portrait of a live person. Practical significance. We report the results of a numerical experiment demonstrating the possibility of transmission of 3D holographic images using standard communication channels intended for application in television and augmented reality without specialized glasses and other devices worn by the observer. This result is based on the proposed method for the separation of the carrier spatial frequency and frequencies containing the information about the holography object.
