Abstract: Systems of the present disclosure may include one or more of an optical overlay device, which may include one or more of an imaging optic to receive incoming light from a scene, and project at least a portion of the incoming light onto an imaging sensor; an imaging sensor to transduce into image data the light projected onto it by the imaging optic; a processing engine electrically coupled with a non-transitory computer readable medium having machine readable instructions stored thereon, which, when executed by the processing engine, cause the system to: generate a scaled overlay image based on the image data and a magnification parameter; a display device configured to project the scaled overlay image through a display optic toward a portion of a beam-combiner; a coupling mechanism to enable releasable attachment of the optical overlay device with a primary viewing device.

Abstract: A dynamic time multiplexed holographic system including a holographic screen and a projector that projects successive perspective images onto the holographic screen. The projector includes a rotating polygon that provides successive image slices to the holographic screen and a spatial light modulator that provides successive image slices to the rotating polygon. The holographic screen refracts the successive perspective images perpendicular to the holographic screen.

Abstract: A collimating screen simulator comprising a projector and a holographic diffuser screen. The projector is adapted to project a viewable image onto a focal plane that is spaced from the projector. The focal plane has a backside and a viewing side opposite the focal plane backside. In operation, the projector is able to project the image onto the focal plane backside. The holographic diffuser screen is adapted to permit light from a source and incident upon a surface of the diffuser screen to pass through the screen. The holographic diffuser screen has a first surface facing the focal plane viewing side for receiving the incident light. The holographic diffuser screen also has a second surface opposite the first surface. The holographic diffuser screen is spaced from the focal plane viewing side by a distance effective for enabling a viewer facing the second surface of the holographic diffuser screen to see collimated light exiting the holographic screen.

Abstract: The invention is directed to an autostereoscopic three-dimensional liquid crystal display system and a method of making the system. The system comprises a collimated backlight, a first light diffracting hologram, a second right-left interlacing hologram and a liquid crystal display. If the backlight is not collimated, a micro-collimator array is used to collimate the backlight prior to passing into the first hologram. The second right-left interlacing hologram is formed through a two step process. The process comprises positioning a photolithographic mask and a view region mask in a first position, recording the first holographic recording in the first position, shifting the photolithographic mask and the view region mask to a second position and recording the second holographic recording in the second position.

Abstract: A beam deflector comprising a pair of mated microprism arrays with one of the arrays comprised of a variable refractive index material capable of being selectively changed in response to a field whose magnitude or intensity is regulated by regulating voltage applied. The other array preferably is comprised of a material having a constant refractive index. A conductive layer is disposed on both sides of the variable refractive index array. A pane preferably is disposed in front and behind the arrays. Two pairs of the arrays can be arranged parallel to each other with their microprisms generally perpendicular forming a two-dimensional deflector. To achieve a deflection response time faster than 100 &mgr;s, each prism has a height no larger than about 20 &mgr;m and a width preferably no greater than about 100 &mgr;m. Preferably, each prism height is less than about 15 to about 10 &mgr;m to achieve a response time 30 &mgr;s or faster.

Abstract: A diffuser based on a phase volume holographic medium is recorded non-holographically with speckle which define non-discontinuous and smoothly varying change in the refractive index of the medium. The diffuser scatters light traveling from an entrance surface to an exit surfaces and reflection from the diffuser is substantially limited to Fresnel reflection from the entrance and exit surfaces and light exiting the exit surface is substantially non-specular.

Abstract: A high finesse holographic Fabry-Perot etalon and method of making a high finesse holographic Fabry-Perot etalon is disclosed. Particularly, a holographic Fabry-Perot etalon which achieves high finesse despite non-flat interfaces between the etalon media is presented. In a preferred method of fabricating a high finesse Fabry-Perot etalon, single step recording of both holograms simultaneously, with the spacer and substrates in place, is employed which preserves full phase synchronization between the holograms. In spite of imperfections or irregularities of the interface surfaces of the substrates or spacers, the holographic fringes in the holograms remain flat even for slightly different refractive indices between the various media. The position and flatness of the fringes remains similar to perfect Fabry-Perot etalon structure.
