Abstract
A compact, lightweight dichoptic display system is provided. The system utilizes a single image generating device which alternately provides low resolution, wide field-of-view images with high resolution, narrow field-of-view images of a specific area of the same scene. The light radiated by the image generating device is linearly polarized. The polarized light passes through a controllable retarder, the retarder imparting a 180 degree phase delay to alternating scenes. Using a polarization sensitive beam splitter, the images generated by the display are directed to alternate eyepieces. Collimating optics are used to insure that the two images appear to be the same distance from the user, therefore enabling the user to properly combine the two images.
