    Abstract: Imaging apparatus includes an illumination assembly, including a plurality of radiation sources and projection optics, which are configured to project radiation from the radiation sources onto different, respective regions of a scene. An imaging assembly includes an image sensor and objective optics configured to form an optical image of the scene on the image sensor, which includes an array of sensor elements arranged in multiple groups, which are triggered by a rolling shutter to capture the radiation from the scene in successive, respective exposure periods from different, respective areas of the scene so as to form an electronic image of the scene. A controller is coupled to actuate the radiation sources sequentially in a pulsed mode so that the illumination assembly illuminates the different, respective areas of the scene in synchronization with the rolling shutter.

    Abstract: A scanning device includes a base containing one or more rotational bearings disposed along a gimbal axis. A gimbal includes a shaft that fits into the rotational bearings so that the gimbal rotates about the gimbal axis relative to the base. A mirror assembly includes a semiconductor substrate, which has been etched and coated to define a support, which is fixed to the gimbal, at least one mirror, contained within the support, and a connecting member connecting the at least one mirror to the support and defining at least one mirror axis, about which the at least one mirror rotates relative to the support.

    Abstract: A scanning device includes a scanner, which includes a base and a gimbal, mounted within the base so as to rotate relative to the base about a first axis of rotation. A transmit mirror and at least one receive mirror are mounted within the gimbal so as to rotate in mutual synchronization about respective second axes, which are parallel to one another and perpendicular to the first axis. A transmitter emits a beam including pulses of light toward the transmit mirror, which reflects the beam so that the scanner scans the beam over a scene. A receiver receives, by reflection from the at least one receive mirror, the light reflected from the scene and generates an output indicative of the time of flight of the pulses to and from points in the scene.

    Abstract: A method for depth mapping includes acquiring first depth data with respect to an object using a first depth mapping technique and providing first candidate depth coordinates for a plurality of pixels, and acquiring second depth data with respect to the object using a second depth mapping technique, different from the first depth mapping technique, and providing second candidate depth coordinates for the plurality of pixels. A weighted voting process is applied to the first and second depth data in order to select one of the candidate depth coordinates at each pixel. A depth map of the object is output, including the selected one of the candidate depth coordinates at each pixel.

    Abstract: A Predictive, Foveated Virtual Reality System may capture views of the world around a user using multiple resolutions. The Predictive, Foveated Virtual Reality System may include one or more cameras configured to capture lower resolution image data for a peripheral field of view while capturing higher resolution image data for a narrow field of view corresponding to a user's line of sight. Additionally, the Predictive, Foveated Virtual Reality System may also include one or more sensors or other mechanisms, such as gaze tracking modules or accelerometers, to detect or track motion. A Predictive, Foveated Virtual Reality System may also predict, based on a user's head and eye motion, the user's future line of sight and may capture image data corresponding to a predicted line of sight. When the user subsequently looks in that direction the system may display the previously captured (and augmented) view.
