摘要： This document describes techniques and apparatuses for implementing a hybrid concentrator for a backlight. The backlight includes a light guide and multiple light sources positioned along an input end of the light guide. The backlight further includes multiple hybrid concentrators that each include a lens in a central region of the concentrator and one or more total-internal-reflection (TIR) zones. Each hybrid concentrator is positioned between a corresponding light source and the light guide, and is configured to concentrate light into the light guide. The light guide then projects the concentrated light to illuminate a modulating display panel to form images for viewing.
摘要翻译：该文献描述了用于实现用于背光的混合集中器的技术和装置。背光包括光导和沿光导的输入端定位的多个光源。背光还包括多个混合集中器，每个混合集中器包括在聚光器的中心区域中的透镜和一个或多个全内反射（TIR）区域。每个混合集中器位于对应的光源和光导之间，并且被配置为将光聚集到光导中。然后光导投影集中的光以照亮调制显示面板以形成用于观看的图像。

摘要： A 3D silhouette sensing system is described which comprises a stereo camera and a light source. In an embodiment, a 3D sensing module triggers the capture of pairs of images by the stereo camera at the same time that the light source illuminates the scene. A series of pairs of images may be captured at a predefined frame rate. Each pair of images is then analyzed to track both a retroreflector in the scene, which can be moved relative to the stereo camera, and an object which is between the retroreflector and the stereo camera and therefore partially occludes the retroreflector. In processing the image pairs, silhouettes are extracted for each of the retroreflector and the object and these are used to generate a 3D contour for each of the retroreflector and object.

摘要： A holographic interaction device is described. In one or more implementations, an input device includes an input portion comprising a plurality of controls that are configured to generate signals to be processed as inputs by a computing device that is communicatively coupled to the controls. The input device also includes a holographic recording mechanism disposed over a surface of the input portion, the holographic recording mechanism is configured to output a hologram in response to receipt of light, from a light source, that is viewable by a user over the input portion.

摘要： An optical waveguide includes a waveguide body and a spatially-varying volume hologram. The volume hologram increases, in a coordinate direction along the volume hologram, an angle of incidence by which light propagating in the waveguide body via total internal reflection is released from the waveguide body. The optical waveguide may form part of an optical system that includes one or more light sources and/or optical sensors.
