Patent ID: 8624961

Claim:
A 3-D display method based on random source constructive interference performed by a processor to prepare data for a 3D screen according to the following steps, said 3D screen contains a number of 3D pixels, whose i th 3D-pixel has a primary amplitude A 0j , a primary phase Φ 0j and is located randomly at position R j : A.: Read in a monochrome discrete 3D image, said monochrome discrete 3D image consists of M discrete voxels with m th voxel located at a position r m , m=1, 2 . . . M; B.: Pick up one voxel m from M voxels readied in step A; C.: Select randomly N 3D pixels from sad 3D screen; D.: For each 3D-pixel j selected in step C, calculate a phase difference Φ cj , m=k j, m ·(r m −R j ), where k j, m is a wave vector of light emitted from said 3D-pixel j toward said voxel m picked up in step B, and take the phase difference Φ cj, m as a phase adjustment that should be performed by said 3D-pixel j to generate said voxel m; E.: For each 3D-pixel j in step C, set a constant A cj, m as an amplitude adjustment it should make to generate said voxel m picked up; F.: For each discrete voxel m readied in step A, repeat step B through step E, record said amplitude adjustment A cj, m and said phase adjustment Φ cj, m ; for each 3D-pixel j in way of complex-amplitude addition, sum up all the recorded amplitude adjustment A cj, m and phase adjustment Φ cj , m , A cj = ∑ m = 1 m = M ⁢ Acj , m exp (Φcj, m)=A cj exp(Φ cj ) and take resulting complex amplitudes A cj 's amplitude A cj and phase Φ cj respectively as a total amplitude adjustments and a total phase adjustment it should make; G.: For each 3D-pixel j, calculate a final phase adjustment Φ j by subtracting said primary phase Φ 0j from said total phase adjustment Φ cj determined in step F, Φ j =Φ cj −Φ 0j and use said total amplitude adjustment A cj determined in step F as a final amplitude adjustment A j , A j =A cj ; said final phase adjustment Φ j and final amplitude adjustment A j are data needed for said 3D screen to control each 3D-pixel's phase and amplitude to display said monochrome discrete 3D image read in step A.
