摘要

A method for eliminating a inhomogeneous brightness perception in the case of the holographic reconstruction of object light points existing three-dimensional scene with spatial light modulation clay means, which are connected to a hologram point - data pattern coded modulator cells, wherein a plurality of, the light modulation tone density that is light beam illuminating means and an array with focusing elements (2n), which an optical fourier - transformation (ft), the light beams onto the eyes at least of a viewer in a fourier - transformations - plane (fp), whereby on the surface of the light modulation clay agent by means of different light beams are illuminated regions (r1, r2, r3), which on the geometric and optical properties of the focusing elements (2n) depend,characterized by the following steps:– in the hologram point - data pattern of the light modulation clay agents are those modulator cells is defined, which lie in an area in which the illumination of the modulator cells from the geometric and optical properties of the edges of the focusing elements (2n) is influenced in such a manner that a viewer perceives light wave front brightness differences in the reconstructed– Calculation means for calculating the defined modulator cells on the basis of the space frequency filtering of the pupil (al), with which local defects in a result of the influencing the reconstruction of the three dimensional scene, when viewing be perceived and– correcting corresponding values in the hologram point - data pattern for encoding of the modulator cells so that the modulator cells to form an interference point, of the corresponding object point of the reconstruction can appear with a unaffected brightness.
