Abstract: Apparatus for mapping includes a radiation source, which is configured to emit at least one beam of radiation, and a detector and optics, which define a sensing area of the detector. A scanner is configured to receive and scan the at least one 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 at least one 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: A method for depth mapping includes projecting a pattern of optical radiation onto an object. A first image of the pattern on the object is captured using a first image sensor, and this image is processed to generate pattern-based depth data with respect to the object. A second image of the object is captured using a second image sensor, and the second image is processed together with another image to generate stereoscopic depth data with respect to the object. The pattern-based depth data is combined with the stereoscopic depth data to create a depth map of the object.

Abstract: Optical scanning apparatus includes a triangular prism, having first and second side faces and a base. A transmitter directs a beam of optical radiation into the prism through the first side face, which refracts the beam so that the optical radiation is incident on and reflects from the base within the prism at a reflection angle that is greater than a total internal reflection (TIR) angle of the prism and exits the prism through the second side face. At least one scanning mirror is positioned to intercept and reflect the beam back into the prism while scanning the beam over an angular range selected such that after refraction of the scanned beam at the second side face, the scanned beam is incident on the base at a transmission angle that is less than the TIR angle and is transmitted out of the prism through the base.

Abstract: Depth-sensing apparatus includes a laser, which is configured to emit pulses of optical radiation toward a scene, and one or more detectors, which 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. Control and processing circuitry is coupled to drive the laser to emit a sequence of the pulses in a predefined temporal pattern that specifies irregular intervals between the pulses in the sequence, and to correlate the output signals with the temporal pattern in order to find respective times of flight for the points in the scene.

Abstract: Mapping apparatus includes a transmitter, which emits a beam comprising pulses of light, and a scanner, which is configured to scan the beam, within a predefined scan range, over a scene. A receiver receives the light reflected from the scene and to generate an output indicative of a time of flight of the pulses to and from points in the scene. A processor is coupled to control the scanner so as to cause the beam to scan over a selected window within the scan range and to process the output of the receiver so as to generate a 3D map of a part of the scene that is within the selected window.

Abstract: A system for object reconstruction includes an illuminating unit, comprising a coherent light source and a generator of a non-periodic pattern. A diffractive optical element (DOE) is disposed in an optical path of illuminating light propagating from the illuminating unit toward an object, thereby projecting the non-periodic pattern onto an object. An imaging unit detects a light response of an illuminated region and generating image data indicative of the object within the projected pattern. A processor reconstructs a three-dimensional (3D) map of the object responsively to a shift of the pattern in the image data relative to a reference image of the pattern.

Abstract: Apparatus for mapping includes an illumination assembly, which projects a line of radiation extending in a first direction across a scene. A detection assembly receives the radiation reflected from the scene within a sensing area that contains at least a part of the line of the radiation, and includes a linear array of detector elements and objective optics, which focus the reflected radiation from the sensing area onto the linear array. A scanning mirror scans the line of radiation and the sensing area together over the scene in a second direction, which is perpendicular to the first direction. Processing circuitry processes signals output by the detector elements in response to the received radiation in order to construct a three-dimensional (3D) map of an object in the scene.
