    摘要： 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.

    摘要： A device including a waveguide having a first waveguide surface and a second waveguide surface parallel to the first waveguide surface is disclosed. The device may include a first light coupling device operatively coupled to the waveguide. The first light coupling device may include a first duct structure and a second duct structure oriented to reflect in-coupled light. Each of the first duct structure and the second duct structure may includes a first planar region and a second planar region parallel to the first planar region and a first surface and a second surface parallel to the first surface. The device may also include a second light coupling device disposed between the first waveguide surface and the second waveguide surface. The second light coupling device may be to positioned to receive reflected in-coupled light from the first light coupling device.
