Claim Text:
1. A head mounted display system comprising at least one retinal display unit said at least one display unit comprising: A) a curved reflector and a frame adapted to position the curved reflector in front of at least one eye of a wearer, said at least one eye defining a pupil, a retina, a fovea and a view direction, B) a first set of at least three visible light lasers, all lasers being co-aligned and adapted to provide a co-aligned, color foveal laser beam, C) a second set of at least three visible light lasers plus an infrared laser, all lasers being co-aligned and adapted to provide a co-aligned, color and infrared retinal laser beam, D) a first two dimensional MEMS laser scanner unit adapted to provide both horizontal and vertical scanning of the co-aligned color laser beam across a portion of the curved reflector in directions so as to produce reflections of the horizontally and vertically scanned color foveal laser beam through the pupil of the eye onto a small portion of the retina, said small portion being less than 20 percent of the retina but large enough to encompass the fovea, said small portion defining a foveal region, E) a second two dimensional MEMS laser scanner unit adapted to provide both horizontal and vertical scanning of the co-aligned color and infrared laser beam across a portion of said curved reflector in directions so as to produce a reflection of the horizontally and vertically scanned color and infrared retinal laser beam through the pupil of the same eye onto a portion of retina corresponding to a field of view of at least 30 degrees×30 degrees, F) an infrared light detector adapted to detect infrared light reflected from the retina and the curved reflector and produce an infrared reflection signal, G) a video graphics input device adapted to provide color video graphics input signals, H) control electronics adapted to:
