Method and device for reconstructing of a three dimensional scene with corrected visibility

摘要

A method for reconstructing of a three dimensional scene,in the art and consists of individual object points are existing 3d scene - and - a computer generated hologram (cgh) in a light modulator (slm) of a holographic display is encoded,in the case of the at least one light source the light modulator with coherentLight source and at least a transformation lens the light is transformed, in which a processor control signals for the encoding and reconstruction, andin the case of which the reconstruction of the 3d - scene of a viewing plane from within a function of the visible region can be seen, characterized in that- the processor (pm) to define the position of individual object points (pn) in the horizontal, vertical and the depth direction in a reconstruction volume (rv), a spatial pattern of dots generated and the object points (pn) with predetermined intensity - and phase values, the approximate the 3d - scene,- within the visible region (sb) of a complex-valued wavefront for each individual object point (pn) is calculated and the intensity values of the object points (pn) with a the individual object points (pn) function as a function of the visible assigned to be multiplied, in order to modified wave fronts of the individual object points (pn) to determine which leads to a common modified wavefront of the object points (pn) are summed up,- the modified wave front in the plane of the light modulator (slm) is transformed, and modified control values for the object points (pn) to calculate, and- in a control means control signals are generated, in order to the cgh in the light modulator (slm) with the modified control values to encode and in the visibility range (sb) for reconstructing the 3d scene - to transform.
