摘要： A system and an apparatus for improving image quality of an object in video telephony are described. The apparatus comprises an image detection unit, an image alignment unit and an image fusion unit. A near infrared light source in the image detection unit illuminates the object, such that the object is front illuminated. An image sensor alongside the near infrared light source generates a near infrared image and a visible image. An image alignment unit aligns the near infrared image and the visible image. An image fusion unit fuses the aligned near infrared image and aligned visible image pair to form a composite image of the object. The composite image of the object has improved image quality, image detail, and a reduction in shadows.

摘要： A display device comprises a polymer dispersed liquid crystal film that includes one or more translucent regions and one or more transparent regions. The back side of the polymer dispersed liquid crystal film is illuminated by collimated light. The front side of the polymer dispersed liquid crystal film is optically coupled to an asymmetric optical diffuser. The asymmetric optical diffuser comprises a plurality of light paths that transmit collimated light emanating through a transparent region of the film, but excludes diffuse light emanating from a translucent region. A preferred asymmetric optical diffuser comprises glass microspheres in a black matrix. In this manner, the asymmetric diffuser substantially improves contrast between a transparent region and a translucent region of a display.

摘要： A liquid crystal display device (10) for forming a display includes a liquid crystal panel (12), a switchable holographic optical element (14), and a reflective holographic optical element (16). Ambient light illuminates a front polarizer (18), which polarizes the ambient light and transmits the polarized light to the liquid crystal cell (20). The liquid crystal cell (20) receives the polarized light and transmits polarized light derived from the incident polarized light to a back polarizer (22). The back polarizer (22) polarizes the light and transmits the light to the switchable holographic optical element (14). While in a first mode, the switchable holographic optical element (14) redirects the light back toward the liquid crystal panel (12) within a first viewing cone (34) to form the display. In a second mode, the switchable holographic optical element (14) is transparent and transmits the light to the reflective holographic optical element (16). The reflective holographic optical element (16) redirects the light back toward the liquid crystal panel (12) in a second viewing cone (36) to form the display. The second viewing cone (36) is preferably narrower than the first viewing cone (34), which increases the intensity of the light within the second viewing cone (36).

摘要： A display device (10) includes a display panel, such as a liquid crystal panel (12), in combination with a reflective holographic optical element (14) that redirects ambient light for illuminating the display. The light redirected by the holographic element is limited to a predetermined spectral band. Fluorescent film (16) is included for absorbing light outside the spectral band of the holographic element and re-emitting light within the spectral band to increase the light redirected by the holographic element and thus increase the apparent brightness of the display.

摘要： A wireless binary coded optical data receiver receives the binary encoded data via a photodiode. The binary encoded data is then supplied to the primary winding of a transformer and thus coupled to the secondary winding of the transformer. The secondary winding is coupled to a transimpedance amplifier wherein the transimpedance amplifier buffers the received binary encoded data. The buffered binary encoded data is then amplitude limited by a limiting circuit.

摘要： An apparatus, system and method for telepresence communications at a virtual location between two or more participants at multiple locations (100, 200). First perspective data descriptive of the perspective of the virtual location environment experienced by a first participant at a first location and feature data extracted from features of a second participant at a second location (210, 220) are processed to generate a first virtual representation of the second participant in the virtual environment from the perspective of the first participant (250). Likewise, second perspective data descriptive of the perspective of the virtual location environment experienced by the second participant and feature data extracted from features of the first participant (230, 240) are processed to generate a second virtual representation of the first participant in the virtual environment from the perspective of the second participant (260). The first and second virtual representations are rendered and then displayed to the first and second participants, respectively (260, 270). The first and second virtual representations are updated and redisplayed to the participants upon a change in one or more of the perspective data and extracted feature data from which they are generated (290, 295). The apparatus, system and method are scalable to two or more participants.

摘要： A liquid crystal display device (10) includes a front polarizer (12), a liquid crystal cell (14), a retardation film (16), a back polarizer (18), and a reflective holographic optical element (20). Diffuse ambient light illuminates the front polarizer (12), which polarizes the ambient light and transmits the polarized light to the liquid crystal cell (14). The liquid crystal cell (14) receives the polarized light and transmits polarized light derived from the incident polarized light to the retardation film (16). The retardation film (16) receives the polarized light and transmits polarized light, including light within a selected spectral band. The back polarizer (18) receives the polarized light from the retardation film (16) and selectively transmits polarized light derived from the incident polarized light. The reflective holographic optical element (20) receives polarized light from the back polarizer (18) and redirects the polarized light toward the back polarizer (18), wherein the light has an effective spectral band that includes light in the selected spectral band.
