## 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.

## Claims

### Claim 1

A near eye display (NED) device with concentric imaging and optical elements comprising:
a display with a spherically curved concave image surface, wherein a first polarizer is disposed on the display;
a spherically and circularly rotating tandem comprised of:
a spherically curved concave composite reflector, and
a spherically curved transparent counter-balance;
a motor-driven driving crank operable to rotate the spherically curved concave composite reflector and the spherically curved transparent counter-balance;
a see-thru spherically curved mirror-polarizer composite comprised of
a mirror at the convex side of the see-thru spherically curved mirror-polarizer composite, and
a second polarizer at the concave side of the see-thru spherically curved mirror-polarizer composite; and
a frame operable to mount the device to a user's head.

### Claim 2 (depends on 1)

The device of claim 1 further comprising:
one or more guides to constrain both
the spherically curved composite reflector and
the spherically curved transparent counter-balance to spherical movements.

### Claim 3 (depends on 1)

The device of claim 1
wherein the display is spherically curved, transparent and concave,
wherein an LCD occluder is disposed on the convex side of the display,
further including: a controller circuit.

### Claim 4 (depends on 3)

The device of claim 3 further comprising:
an occluding optical system.

### Claim 5 (depends on 1)

The device of claim 1
wherein the display is cylindrically curved,
wherein a fiber-optic faceplate is disposed on a concave side of the display,
wherein the first polarizer is disposed on a concave surface of the fiber-optic faceplate.

### Claim 6 (depends on 5)

The device of claim 5
wherein the display is transparent and cylindrically curved,
wherein an LCD occluder is disposed on a convex side of the display,
wherein a second fiber-optic faceplate is disposed on a convex side of the LCD occluder,
further comprising: an occluding optical system,
wherein the occluding optical system is disposed on the convex side of the first polarizer.

### Claim 7

An imaging device comprising:
a curved display with a convex surface and a concave surface, the curved display operable to display an image on the concave surface;
a polarizer coupled to the concave surface;
a movable frame coupled to a motor-driven driving crank;
a curved composite reflector disposed on the movable frame, the curved composite reflector including an array of alternating mirror-quarter-wavelength retarder strips and clear optical slits; and
a control circuit operable to control one or both of the image on the curved display or the motor-driven driving crank.

### Claim 8 (depends on 7)

The device of claim 7 further comprising:
a motor-driven counter-balance including a curved transparent counter-balance,
wherein the motor-driven counter-balance is optically aligned to the curved composite reflector.

### Claim 9 (depends on 8)
