METHOD FOR THE COMPENSATION OF AN INHOMOGENEOUS BRIGHTNESS PERCEPTION IN HOLOGRAPHICALLY RECONSTRUCTED SCENES

摘要

to compensate for non-uniform brightness on the recognition of the holographic reconstruction of a 3D scene (4), computing means encodes the modulator cells of the SLM with the hologram data dot pattern. A plurality of light beams are illuminating the surface of the SLM, and the array of focusing elements (21, 23) causes the light beam irradiation of the eye position of the observer. Geometrical and optical properties of the array are affected differently, the illuminated area on the SLM surface. Computing means by combining the expected spatial filtering in the eye of the eye pupil of the observer to determine the parameters that describe the extent of this effect. Using these parameters, the calculation means in the estimation, and the calibrated uniform illumination level is going to be recognized by the observer when the reconstruction error in part of the reconstructed view of the reconstruction caused by the illuminated area affected differently Calibrate the hologram point data pattern to appear.
