摘要： Systems and methods for reducing glare from a heads-up display (HUD). Internal and external antireflective coatings may be provided on interior and outer surfaces of glass layers surrounding a holographic polymer layer. A substrate guided hologram may be integrated into a HUD to diffract and direct external radiation to the edge of a HUD. An arrangement for forming a substrate guided hologram includes an array of reflectors and a shaped glass block. Antireflective coated glass layers may be index-matched to opposite sides of a holographic polymer film prior to recording a reflection hologram. An inactive playback beam may be used to monitor the diffraction efficiency of a reflection hologram and of a spurious transmission hologram with the recording of the reflection hologram to maximize the difference between the diffraction efficiencies of useful reflection hologram and spurious transmission hologram.

摘要： This application relates to a see-through head-mounted display using recorded substrate-guided holographic continuous lens (SGHCL) and a scanning laser beam that creates an image on a diffuser or a microdisplay with laser illumination. The high diffraction efficiency of the volume SGHCL creates very high luminance of the virtual image.

摘要： An illumination system converting light beams into wide-angle light transmissions including i) a cylindrical member having a cone-shaped depression in a distal end; and ii) a semi-circular member having an inner radial surface adjacent to a sidewall of the cylindrical member; and angled upper and lower annular surfaces extending from the cylindrical member and meeting at an outer radial edge. A light beam entering the proximal end of the cylindrical member strikes a first edge of the cone-shaped depression and is reflected out as a first light transmission; or it strikes a second edge of the cone-shaped depression, is reflected against the upper and lower annular surfaces, and exits the cylindrical member as a second light transmission parallel to the first diffused light transmission. At least one light path passes through a diffuser on the cylindrical member.

摘要： The present disclosure provides an anticounterfeiting system based on optical technology that verify the authenticity of protected cinema screens. The optical technology includes taggants embedded or attached to the screen and an optical readout system that can interrogate the taggant layer and receive the taggant output. The taggants are capable of reflecting a pattern that unambiguously demonstrates that the screen contains the taggant. The taggants are covert because they are not visible under normal lighting conditions or during cinema operation, but are detected when interrogated by the optical readout system.

摘要： A holographic substrate-guided wave-based see-through display can has a microdisplay, capable of emitting light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the image from the microdisplay, and capable of transmitting the light. The holographic optical element couples its output to an elongate substrate, capable of accepting the light from the holographic lens at a first location, and transmitting the light along a length of the substrate by total internal reflection to a second location, the elongate substrate being capable of transmitting the accepted light from the second location. The substrate couples out what it receives to a transparent holographic optical element, capable of accepting the light transmitted from the substrate and transmitting it to a location outside of the holographic optical element as a viewable image.

摘要： A large coherent two-dimensional (2D) spatial filter array (SFA), 30 by 30 or larger, is produced by coupling a 2D planar lightwave circuit (PLC) array with a pair of lenslet arrays at the input and output side. The 2D PLC array is produced by stacking a plurality of chips, each chip with a plural number of straight PLC waveguides. A pupil array is coated onto the focal plane of the lenslet array. The PLC waveguides are produced by deposition of a plural number of silica layers on the silicon wafer, followed by photolithography and reactive ion etching (RIE) processes. A plural number of mode filters are included in the silica-on-silicon waveguide such that the PLC waveguide is transparent to the fundamental mode but higher order modes are attenuated by 40 dB or more.

摘要： The optical diffuser mastering of the subject invention includes legacy microstructure surface relief patterns, along with smaller ones, overlaid on the larger ones. The characteristic features produced by the present invention will be found useful to eliminate visible structures in/on optical diffusers, such as those used in movie projection screens (utilizing either coherent (i.e., laser-generated) and non-coherent (e.g., lamp-generated) light), head-up displays (HUDs), laser projection viewing, etc., as the present invention produces much sharper images than those afforded by traditional holographic optical diffusers.

摘要： An array of microstructures or frustums on a substrate for reducing glare for electronic device displays or windows. The microstructures are designed to nearly perfectly align with the pixels on the display to avoid adverse viewing effects, such as Moiré effects. Substantially all light from the environment illuminating the front side of the film containing the microstructures from all angles is not reflected to the primary viewer (often viewing at an angle normal to the film). Light illuminating the microstructure from the environment will reflect off the microstructures at angles greater than a defined threshold outside the primary viewers field of view. Thus, glare to the primary viewer is minimized while glare to other views who view from other angles than the primary viewer is increased. This increased glare for other viewers adds privacy for the viewing by the primary viewer.
