At the time of mannered null holographic displaying which compensates the uneven brightness perception in the scene which

摘要

In order to compensate for uneven brightness perception holographic reconstruction of a 3D scene (4), computing means, encodes the modulator cells of the SLM by the hologram pattern data points. Plurality of light beams illuminating the surface of the SLM, the array of focusing elements (21, 23) turn to the position of the viewer's eye a light beam. Optical properties and geometrical characteristics of the array, causing the surface of the SLM illuminated area affected in various ways. In conjunction with spatial filtering to be expected at the pupil of the viewer's eye, calculating means determines a parameter indicating the degree of these effects. Using these parameters, one of the local error in the reconstruction caused by the illuminated area affected by these various computing means, the local error to be identified by an observer when viewing the reconstituted correcting the data points hologram pattern to appear in the brightness uniformity level is estimated, the corrected reconstruction.
