摘要： A three dimensional imaging apparatus may be used as a microscope or camera. The apparatus includes an array of lenses, each of which is aligned with a respective photodetector element. A liquid crystal spatial light modulator has several pixels between each photodetector element and lens. A control circuit controls the modulator so that the pixels in front of each photodetector element act as a moving shutter. The outputs of the photodetector elements are processed and stored to form a three dimensional image.

摘要： A privacy display comprises a spatial light modulator and a compensated switchable liquid crystal retarder arranged between first and second polarisers arranged in series with the spatial light modulator. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss, whereas off-axis light has reduced luminance. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction over a wide polar field. In a wide angle mode of operation, the switchable liquid crystal retardance is adjusted so that off-axis luminance is substantially unmodified.

摘要： An integrated electro-optical device according to the invention comprises a pixellated liquid crystal modulation layer superimposed over an electronic detection layer. Modulator pads for the liquid crystal layer may be formed as electrically conductive combs to achieve optical polarization. Where the liquid crystal layer provides selective absorption of unpolarized light, and separate polarizers between the liquid crystal and detection layers are therefore unnecessary, the device comprises such a liquid crystal layer superimposed over the electronic detector layer. Further, an integrated electro-optical device, optionally of the above type, has a plurality of pixels of the liquid crystal layer for each pixel of the detector array. This allows optical shuttering of the detector pixels by electrically modulating the pixellated liquid crystal layer.

摘要： Disclosed is an optical valve or light valve for providing large area collimated illumination from localized light sources, and system and method thereof for 2D, 3D, and/or autosteroscopic displays. An optical valve may include a stepped structure, in which the steps include separated extraction features which may be optically hidden to light propagating in a first direction. Light propagating in a second direction may be refracted, diffracted, or reflected by the features to provide illumination beams exiting from the top surface of the optical valve. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays as well as improved 2D display functionality.

摘要： A polarization conversion system (PCS) is located in the output light path of a projector. The PCS may include a polarizing beam splitter, a polarization rotating element, a reflecting element, and a polarization switch. Typically, a projector outputs randomly-polarized light. This light is input to the PCS, in which the PCS separates p-polarized light and s-polarized light at the polarizing beam splitter. P-polarized light is directed toward the polarization switch on a first path. The s-polarized light is passed on a second path through the polarization rotating element (e.g., a half-wave plate), thereby transforming it to p-polarized light. A reflecting element directs the transformed polarized light (now p-polarized) along the second path toward the polarization switch. The first and second light paths are ultimately directed toward a projection screen to collectively form a brighter screen image in cinematic applications utilizing polarized light for three-dimensional viewing.
