Abstract: Imaging apparatus includes an image capture device, which includes an optical transmitter, which is configured to emit one or more pulses of infrared radiation toward an area containing a body surface of a living subject, and an optical receiver, which is configured to receive the pulses reflected from the body surface and to generate an output indicative of a modulation of the pulses by tissue below the body surface. A processor is configured to generate, based on the modulation of the pulses, an image of blood vessels located beneath the body surface within the area.

Abstract: Imaging apparatus includes an image sensor, which acquires an image of a scene, and a scanner, which includes an optical transmitter, which emits a sequence of optical pulses toward the scene, and an optical receiver, which receives the optical pulses reflected from the scene and generates an output indicative of respective times of flight of the pulses. Scanning optics are configured to scan the optical pulses over the scene in a scan pattern that covers and is contained within a non-rectangular area within the scene. A processor identifies an object in the image of the scene, defines the non-rectangular area so as to contain the identified object, and processes the output of the optical receiver so as to extract a three-dimensional (3D) map of the object.

Abstract: Embodiments described include a system comprising a position sensing device (PSD) and a light source. The light source is configured to, by passing one or more light beams through the PSD, cause one or more electrical currents to flow through the PSD. The system further comprises a processor, configured to (i) in response to the electrical currents, ascertain an amount of power that is delivered by the light source, and (ii) in response to the amount of power exceeding a threshold amount of power, inhibit the light source from further operation. Other embodiments are also described.

Abstract: A light beam scanning device includes a controller device which dynamically adjusts a divergence of the beam. Divergence adjustment can include adjusting the beam divergence along one or more cross sectional axes of the beam. Beam divergence can be adjusted between consecutive scans, during a scan, etc. Beam divergence can be adjusted based on the field of view and scan rate. Beam divergence adjustment can enable dynamic adjustment of the spot size of the beam, which can enable the apparatus to adjust between scanning a wide divergence beam to detect objects in a scene and scanning a narrow divergence beam to generate detailed point clouds of the detected objects. Beam divergence adjustment can enable adjustment of reflection point intensity, enabling detection of low-reflectivity objects.
