<p>The invention relates to an analytical method for computing a video holog ram for a holographic reproduction device (HAE) having at least one light mo dulation means (SLM), wherein a scene (3D-S) split into object points (OP) i s encoded as a whole hologram (H~SLM) and can be seen as a reconstruction fr om a visibility region (VR), which is located within a periodicity interval of the reconstruction of the video hologram. The visibility region (VR), tog ether with each object point (OP) of the scene (3D-S) to be reconstructed, d efines a subhologram (SH) and the whole hologram (H~SLM) is generated from a superposition of subholograms (SH), wherein the complex hologram values of a subhologram (SH) are determined from the wave front of the respective obje ct point (OP) to be reconstructed in a modulator region (MR) of the light mo dulation means, by calculating and evaluating the transmission or modulation functions of an imaging element (OS) formed in the modulator region (MR). T he object point (OP) to be reconstructed is located in the focal point of th e imaging element.</p> |
