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.

[ I claim:] [1.] A dichoptic display apparatus, comprising:an image source generating linearly polarized image light, wherein said image source alternates at a predetermined rate between images of a first type and images of a second type, wherein said first type of image is a low resolution, wide field-of-view image and said second type of image is a high resolution, narrow field-of-view image of a portion of said first type of image;a retarding element, wherein said retarding element alters at an integral multiple of said predetermined rate the phase of said polarized image light between a first phase and a second phase; anda first beam splitter, wherein said first beam splitter reflects image light of said first phase to a first viewing site and passes image light of said second phase to a second viewing site.
