Digital methods of forming holograms

Application of holography methods open new possibilities of constructing holographic television systems (HTS) that provide salient, multi-angle and interference-resistant images of extended scenes and three-dimensional objects. HTS, which synthesizes three-dimensional holograms and restore the images of three-dimensional objects, can be realized thanks to obtaining the third coordinate (the scene depth) by means of the laser with a linearly tunable frequency, which corresponds to synthesizing multi-frequency systems [1]. Figure 1 shows a flowchart of the HTS, which synthesize three-dimensional holograms.
