DUAL-DIRECTION COLLIMATOR |
摘要 |
Dual-direction collimation and a dual-direction optical collimator provide dual-direction collimated light at a non-zero propagation angle. The dual-direction collimator includes a vertical collimator configured to collimate light in a vertical direction and a horizontal collimator configured to collimate the vertically collimated light in a horizontal direction. The horizontal collimator is located at an output of the vertical collimator. A three-dimensional (3D) display includes the dual-direction collimator, a plate light guide and an array of multibeam diffraction gratings at a surface of the plate light guide to couple out the dual-direction collimated light guided in the plate light guide as a plurality of light beams corresponding to different 3D view of the 3D electronic display. |
