摘要： A method for constructing a 3D representation of a subject comprises capturing, with a camera, a 2D image of the subject. The method further comprises scanning a modulated illumination beam over the subject to illuminate, one at a time, a plurality of target regions of the subject, and measuring a modulation aspect of light from the illumination beam reflected from each of the target regions. A moving-mirror beam scanner is used to scan the illumination beam, and a photodetector is used to measure the modulation aspect. The method further comprises computing a depth aspect based on the modulation aspect measured for each of the target regions, and associating the depth aspect with a corresponding pixel of the 2D image.

摘要： Techniques are provided for determining distance to an object in a depth camera's field of view. The techniques may include raster scanning light over the object and detecting reflected light from the object. One or more distances to the object may be determined based on the reflected image. A 3D mapping of the object may be generated. The distance(s) to the object may be determined based on times-of-flight between transmitting the light from a light source in the camera to receiving the reflected image from the object. Raster scanning the light may include raster scanning a pattern into the field of view. Determining the distance(s) to the object may include determining spatial differences between a reflected image of the pattern that is received at the camera and a reference pattern.

摘要： An optical tracking system is disclosed that provides more precise tracking and better performance in an optical mouse. It involves provides a collimated laser, and imaging a reflection of the collimated laser, such that the reflection has a substantially linear phase gradient. The reflection of the laser includes a pattern of speckles due to optical interference effects. The speckles are imaged such that the substantially linear phase gradient restricts any variation in intensity of the imaging of the speckles during a translating motion of the reflection, thereby providing superior tracking performance.
