Dynamic foveal vision display

摘要

A head mounted display system with at least one retinal display unit having a curved reflector positioned in front of one eye or both eyes of a wearer. The unit includes a first set of three modulated visible-light lasers co-aligned and adapted to provide a laser beam with selectable color and a first scanner unit providing both horizontal and vertical scanning of the laser beam across a portion of the curved reflector in directions so as to produce a reflection of the color laser beam through the pupil of the eye onto a portion of the retina large enough to encompass the fovea. The unit also includes a second set three modulated visible-light lasers plus an infrared laser, all lasers being co-aligned and adapted to provide a color and infrared peripheral view laser beam, and a second scanner unit providing both horizontal and vertical scanning of the visible light and infrared laser beams across a portion of the curved reflector in directions so as to produce a reflection of the scanned color and infrared laser beams through the pupil of the eye onto a portion of retina corresponding to a field of view of at least 30 degrees×30 degrees.
