Abstract
A near-eye display that employs rapid spherical image scanning using liquid crystal retarder with concentric imaging and optical elements comprising a display with spherically curved concave image surface topped with a first polarizer; a spherically curved liquid crystal retarder composite reflector having a see-thru mirror topped at the concave side with electronically controlled liquid crystal retarder strips; a see-thru spherically curved mirror-polarizer composite with a mirror at the convex side and a second polarizer at the concave side; a frame to support, protect the device, and mount the device to the head.
Claims6
A near eye display device comprising;
- a frame with concentric imaging and optical elements with said imaging element having a spherically curved concave image surface topped with a first polarizer;
- a spherically curved composite reflector, said composite reflector including a plurality of strips of liquid crystal retarder, said strips coupled to a controller circuit at the concave side, said composite reflector also including a see-thru mirror disposed on the convex side;
- a see-thru spherically curved mirror-polarizer composite, said mirror-polarizer composite including a see-thru mirror at the convex side and a second polarizer at the concave side;
- wherein the frame is operable to mount the device to a user's head.
