Patent number: 5410371Abstract: An acousto-optic tunable filter (AOTF) is employed to generate a display by driving the AOTF with an RF electrical signal comprising modulated red, green, and blue video scan line signals and scanning the AOTF with a linearly polarized, pulsed light beam, resulting in encoding of color video columns (scan lines) of an input video image into vertical columns of the AOTF output beam. The AOTF is illuminated periodically as each acoustically-encoded scan line fills the cell aperture of the AOTF. A polarizing beam splitter removes the unused first order beam component of the AOTF output and, if desired, overlays a real world scene on the output plane. Resolutions as high as 30,000 lines are possible, providing holographic display capability.Type: GrantFiled: June 7, 1993Date of Patent: April 25, 1995Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: James L.
