Abstract:
1. A stereoscopic apparatus, comprising: (A) a matrix polarization encoding device, that has M rows and N columns; and (B) a polarization selector, that is arranged sequentially on the same optical axis as the matrix polarization encoding device; wherein (a) outputs of the selector are optically connected with left and right observation areas, (b) a transfer characteristic for a mn-th element of the matrix polarization encoding device is determined by an inverse trigonometric function of a ratio of an algebraic relation of B (c) the matrix polarization encoding device comprises a working medium that has mutually orthogonal directions of optical anisotropy for each pair of adjacent columns of the matrix polarization encoding device; and (d) the polarization selector comprises a working medium comprising electrically addressable columns such that one of the following conditions is satisfied:
