    Abstract: Depth mapping apparatus includes an illumination assembly, which directs modulated optical radiation toward a target scene, and a camera, which captures a two-dimensional image of the target scene. A range sensor senses respective times of flight of photons reflected from a matrix of locations disposed across the target scene. A processor derives first depth coordinates of the matrix of locations responsively to the respective times of flight, derives second depth coordinates of the matrix of locations responsively to a transverse disparity between features in the two-dimensional image and corresponding reference features in a reference image, computes a disparity correction function based on a difference between the first and the second depth coordinates at the matrix of locations, corrects the transverse disparity between the two-dimensional image and the reference image using the disparity correction function, and generates a depth map of the target scene based on the corrected transverse disparity.

    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: Scanning apparatus includes a transmitter, which is configured to emit a beam comprising pulses of light, and a scanner, which is configured to scan the beam along a scan axis over a specified angular range. A scattering line extends across a path of the scanned beam. A receiver is configured to receive the light scattered from the scattering line and to generate an output indicative of an intensity of the scattered light. A controller is coupled to process the output of the receiver so as to monitor operation of the scanner.
