Near-Eye-Display (NED) that Employs Rapid Spherical Image Scanning
First Claim
1. A near eye display (NED) device comprising;
- a frame with concentric imaging and optical elements said imaging element having a spherically curved concave image surface topped with polarizer;
a spherically and circularly rotating tandem of a spherically curved concave composite reflector, and a spherically curved transparent counter-balance;
means to rotate the composite reflector and its counter-balance;
a see-thru spherically curved mirror-polarizer composite with mirror at the convex side and polarizer at the concave side;
a frame to support, protect the device, and mount the device to the head.

Abstract
A NED-RapSIS with concentric imaging and optical elements comprising a display with spherically curved concave image surface topped with polarizer; a spherically curved concave composite reflector having polar arrayed alternating mirror-quarterwavelength retarder strips, and clear optical slits; a spherically curved transparent counter-balance; a motor-driven driving crank near the edges that drives the reflector and counter-balance to circular-spherical movement; a slave crank near the opposite edge of composite reflector with its shaft and crank arms aligned to the concentric center another slave crank near the opposite edge of the counter-balance with its shaft and crank arms aligned with the shaft and crank arms respectively of the latter crank and aligned with the concentric center; a see-thru spherically curved mirror-polarizer composite with mirror at the convex side and polarizer at the concave side, and a support frame.
