Near-eye-display with rapid spherical image scanning
View Patent ↗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.
1. 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.
2. The device of claim 1 wherein the said display device further includes an LCD occluder disposed on the convex side, said occlude coupled to a second controller circuit.
3. The device of claim 2 further including an external viewing system.
4. The device of claim 3 further including one or more guides operable to constrain said composite reflector and a counter balance of said external viewing system to spherical movements.
5. The device of claim 1 wherein said display device includes a fiber-optic faceplate on the concave side wherein the concave surface of the fiber-optic faceplate is topped with said first polarizer.
6. The device of claim 5 wherein said display device includes an LCD occluder coupled to the convex side with a second fiber-optic faceplate.
