Head worn display with foveal and retinal display

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:
• 1) determine the view direction of the eye based on the infrared reflection signal,
• 2) modulate the first set of three visible light lasers based on the video graphics input signals and control the first scanner unit based on the infrared reflection signal to produce, with the scanned foveal laser beam, color images on the foveal region of the eye, and
• 3) modulate the second set of three visible light lasers based on the video graphics input signals and control the second scanner unit based on the infrared reflection signal to produce, with the retinal color and infrared laser beam:
• a) color images on a region of the retina corresponding to a field of view of at least 30 degrees×30 degrees and
• b) infrared reflected light for determining the eye view direction wherein the first scanner unit is adapted to produce a relatively high resolution image on the fovea region of the user's eye and the second scanner unit is adapted to produce a substantially larger image on a portion of the user's eye providing the user a high resolution image of objects within less than 20 degrees of the center of his field of view and an overall field of view of at least 30 degrees.
