Abstract: An electro-optical device includes a laser, which is configured to emit toward a scene pulses of optical radiation. An array of detectors are configured to receive the optical radiation that is reflected from points in the scene and to output signals indicative of respective times of arrival of the received radiation. A controller is coupled to drive the laser to emit a sequence of pulses of the optical radiation toward each of a plurality of points in the scene and to find respective times of flight for the points responsively to the output signals, while controlling a power of the pulses emitted by the laser by counting a number of the detectors outputting the signals in response to each pulse, and reducing the power of a subsequent pulse in the sequence when the number is greater than a predefined threshold.

Abstract: Apparatus for mapping includes a radiation source, which is configured to emit a beam of radiation, and a detector and optics, which define a sensing area of the detector. A scanning mirror assembly is configured to receive and scan the emitted beam over a selected angular range within a region of interest while scanning the sensing area over the selected angular range in synchronization with the scanned beam from the radiation source. A processor is configured to process signals output by the detector in order to construct a three-dimensional (3D) map of an object in the region of interest.

Abstract: Apparatus for mapping includes a radiation source, which is configured to emit a beam of radiation. A first scanning mirror is configured to receive and scan the emitted beam in a first direction over a selected angular range within a region of interest. A detector and optics define a sensing area of the detector. A second scanning mirror is configured to scan the sensing area over the selected angular range in the first direction in synchronization with the scanned beam from the radiation source. A scanner is configured to scan both the emitted beam and the sensing area over the region of interest in a second direction, which is perpendicular to the first direction. A processor is configured to process signals output by the detector in order to construct a three-dimensional (3D) map of an object in the region of interest.

Abstract: An optical device includes a first array of emitters disposed on a substrate and configured to emit respective beams of optical radiation in a direction perpendicular to the substrate. A second array of microlenses is positioned on the substrate in alignment with the respective beams of the emitters, having respective sag profiles that vary over an area of the substrate. The second array includes at least first microlenses in a central region of the substrate and second microlenses in a peripheral region of the substrate, such that the first microlenses have respective first focal powers, while the second microlenses have respective second focal powers, which are less than the first focal powers.

Abstract: Control apparatus includes an optical subsystem, which is configured to direct first light toward a scene that includes a hand of a user in proximity to a wall of a room and to receive the first light that is reflected from the scene, and to direct second light toward the wall so as to project an image of a control device onto the wall. A processor is configured to control the optical subsystem so as to generate, responsively to the received first light, a depth map of the scene, to process the depth map so as to detect a proximity of the hand to the wall in a location of the projected image, and to control electrical equipment in the room responsively to the proximity.
