An optical system for a camera includes a convex reflector, a decompression lens, and an image sensor. The convex reflector has a first diameter and a non-parabolic, axially symmetric, aspheric surface that provides a virtual curved and compressed image of a scene having a non-parabolic image compression. The decompression lens is positioned to receive the virtual curved and compressed image. The decompression lens is configured to decompress the virtual curved and compressed image into a real image having a parabolic image decompression and project the real image. The image sensor is positioned to receive the real image. The real image has a second diameter at the image sensor that is less than the first diameter. A ratio of the first diameter to the second diameter is between 6.5:1 and 2.3:1. The optical system provides a polychromatic modulation transfer function of 30% or more for 150 cy/mm.

An image display device according to an embodiment of the present technology include an emission portion, an irradiation target, and an optical portion. The emission portion emits image light along a predetermined axis. The irradiation target is disposed at at least a part around the predetermined axis. The optical portion controls an incident angle of the image light on the irradiation target, the image light having been emitted from the emission portion, the optical portion being disposed in a manner that the optical portion faces the emission portion on the basis of the predetermined axis.

One embodiment provides an imaging device, including: a sparsely-filled optical aperture having a shape forming an outer portion of the optical aperture, wherein at least a portion of an inner portion formed by the outer portion of the optical aperture is not a part of the optical aperture; and imaging optics, wherein the imaging optics include at least one reflection device optically located after the optical aperture and at least one imaging sensor optically located after the at least one reflection device, wherein light entering the optical aperture reflects from the at least one reflection device onto the at least one imaging sensor. Other embodiments are described herein.

An apparatus and method for optically remapping projected pixels to maximize the utilization and to optimize the distribution of remapped projection pixels to achieve optimal visual performance (generally uniform resolution and luminance). A device interposed between a projector and an imaging surface for optically remapping projected pixel locations with minimal aberration. When this device is interposed between a projector and an imaging surface, it changes the terminal location of each focused pixel such that it maximally coincides with the imaging surface, which is often a surface of complex curvature and very different from the native focal surface of the projector. One implementation of the technology includes a device that uses multiple optical surfaces.
