Abstract:
1. A near-eye display system comprising: a light source; a first polarizing beam splitting surface disposed downstream of the light source along an optical path of the near-eye display system, the first polarizing beam splitting surface being configured to receive light from the light source; a mirror disposed downstream of the first polarizing beam splitting surface along the optical path, the mirror configured to reflect light passed by the first polarizing beam splitting surface back toward the first polarizing beam splitting surface; a quarter wave plate positioned between the first polarizing beam splitting surface and the mirror along the optical path; a second polarizing beam splitting surface disposed downstream of the first polarizing beam splitting surface and the mirror along the optical path, the second polarizing beam splitting surface being positioned at an angle relative to the first polarizing beam splitting surface; and a microdisplay disposed downstream of the second polarizing beam splitting surface along the optical path, the microdisplay configured to produce an image from light received from the second polarizing beam splitting surface.
