摘要： A device includes a projection and camera system to create an augmented reality environment in which images are projected onto a scene and user movement within the scene is captured. The projection and camera system have a camera to image scattered IR light from the scene and compute time of flight values used in depth mapping of objects in the room. The system also has a projector to project the images onto the scene. The projected images and scattered IR light use a common optical path through the same lens. Additionally, an illumination system used to illuminate the scene with the IR light may also use the common optical path through the same lens. In one implementation, the projection and camera system are mounted in a movable head of a table lamp.

摘要： Two or more imagers having associated frame rates are each configured with a global shutter having an exposure interval less than a frame interval. The exposure interval for a first imager is offset from the exposure interval of a second imager such that the first imager is exposed while the second imager is not exposed. When interleaved, an effective frame rate exceeds the individual frame rates provided by the individual imagers. This interleaved imaging system may be used to recover, at high frame rates, images that are projected from spatial light modulators.

摘要： A directive projection screen is configured to present images projected from a remote projector in three dimensions (3D) to a viewer. The screen includes a plurality of passive optical elements arranged on a structural substrate. The optical elements are configured to receive incident light projected from the projector and reflect the light such that first portions of the image are directed in a first direction to be viewed by a first eye of the viewer and second portions of the image are directed in a second direction to be viewed by a second eye of the viewer.

摘要： A sample substrate for use in a fluorescence imaging system includes a rigid base with a specularly reflective surface, typically metal, on which is deposited a transparent coating layer. The coating layer has a thickness selected so that a particular fluorescence excitation wavelength, corresponding to a specified fluorescent constituent to be sought in sample material, has an optical path from the top of the coating layer to the reflecting surface in the base of substantially an odd multiple of one-quarter wavelength, so that the standing wave of the fluorescence excitation wavelength of light incident on the substrate has an antinode located at or near where sample material would be disposed on top of the coating layer. This maximizes fluorescence excitation of the sample on the reflective substrate. The transparent coating layer may be a dielectric material (e.g. silica) or may be a multilayer structure with a top layer of biologically active material for binding a specified sample constituent.

摘要： Within a particular environment, a projection that may include light or one or more patterns may be directed at one or more mirrors. The projection may be reflected by a first one of the mirrors onto the surroundings of the environment, which may include a floor, one or more walls, and/or objects in the environment having a surface. A second mirror may represent an entire view of the surroundings of the environment. As a result, by taking an image directed at the second mirror, a single image may be captured that represents a view of the entire environment without having to rotate the device that captures the image. The single image may then be utilized to generate a three-dimensional model of the environment.
