Abstract: A holographic substrate-guided wave-based see-through display 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 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 optical element at a first location, and transmitting the light along a length of the substrate by 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.

Abstract: A laser image projector display system (200) includes laser operating electronics (208, 210, 212, 400, 500, 700) that selectively operates a laser diode at a bias that is low enough to save energy based on analysis pixel brightness values. The laser bias may be high enough that laser can be transitioned to a lasing state in time to display a pixel, or the system can “look ahead” into a stream of pixels and adjust the bias in advance.

Abstract: An optical reflecting device employs an interfacing of an optical refractor and an optical reflector. When incorporated within a system (e.g., an optical switch, a display, and a bar code scanner), the optical reflecting device can be rotated among a plurality of positions. At a first position of the optical reflecting device, a light beam entering the optical reflecting device is sequentially refracted by the optical refractor, reflected by the optical reflector and refracted by the optical refractor prior to exiting the optical reflecting device at a first exit angle of the light beam from a normal axis of the optical reflector. Upon a rotation of the optical reflecting device by a rotation angle to a second rotation position, the light beam exits the optical reflecting device at a second exit angle of the light beam from the normal axis of the optical reflector at the first rotation position. An absolute value of a difference between the first and second exit angles is greater than twice an absolute value of the rotation angle.

Abstract: A head-up display includes an image source, such as a laser scanner, a means for diffusing light and a transparent element that can include a holographic element. The laser scanner emits a visible light for generating an image. The means for diffusing light receives the visible light from the laser scanner to project the image thereon, and preferably apply gain thereto. The transparent element produces a virtual or a real image of the image from the means for diffusing light. In a vehicle, the head-up display is configured to reflect the image into the vehicle to provide a virtual image ahead of a driver.

Abstract: A liquid crystal device comprises a first and second cell wall structure; at least one liquid crystal material disposed within a space between the first and second cell wall structures; and polymer micro-structures, wherein the micro-structures are formed by polymerizing a prepolymer, and wherein said micro-structures have a shape and spatial location determined by said liquid crystal material. Permanent polymer micro-structures are formed from a liquid crystal with a non-uniform spatially modulated director field. The polymer structures have the shape and spatial location dictated by the non-uniform director field of the liquid crystal. The micro-structures are a backbone that restores the liquid crystal director field that existed during the polymerization process even when other factors, such as electric field, temperature, or surface anchoring, do not favor this restoration. The polymer micro-structures can be used in optical devices, such as diffraction gratings and deflecting and beam steering devices, and in micro-mechanical and micro-fluidic devices.

Abstract: A substrate-guided holographic diffuser has a light-guide section configured to in-couple light and transmit the light within itself via total internal reflection. It can also have a brightness enhancement section that recycles non-diffracted light within the light-guide section. A hologram section that receives light from the light-guide section has a holographic structure defining acceptance conditions and is positioned relative to the internally reflected light such that the internally reflected light meets the acceptance conditions of the holographic structure. The internally reflected light is out-coupled by the holographic structure as a projected image of light scattered from a diffuser.
