    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: Imaging apparatus includes a housing, with imaging optics mounted in the housing and configured to form an optical image, at a focal plane within the housing, of an object outside the housing. An image sensor, including a matrix of detector elements, is positioned at the focal plane in alignment with the imaging optics and is configured to output an electronic image signal in response to optical radiation that is incident on the detector elements. At least one emitter is fixed within the housing and is configured to emit a test beam toward one or more reflective surfaces within the housing, which reflect the test beam toward the image sensor. A processor is configured to process the electronic image signal output by the image sensor in response to the reflected test beam so as to detect a change in the alignment of the image sensor with the imaging optics.

    Abstract: An opto-electronic device includes a semiconductor substrate having a planar surface. An emitter is formed on the substrate and configured to emit a beam of light away from the planar surface. A reflective layer is formed on the planar surface adjacent to the emitter. A transparent layer is formed over the planar surface and has a curved outer surface including a first segment positioned vertically over the emitter and configured to internally reflect the emitted beam of light toward the reflective layer, and a second segment positioned and configured to collimate and transmit the beam reflected from the reflective layer.
