Abstract: A time of flight detector includes an electromagnetic radiation emitter configured to emit a beam of radiation. A first optical element receives the beam of radiation and generates a collimated beam of radiation. A second optical element defines a narrow imaging field of view sufficient to capture reflected electromagnetic radiation from the collimated beam. An electromagnetic radiation sensor then senses the captured reflected electromagnetic radiation from the collimated beam in the narrow imaging field of view. Further narrowing of the imaging field of view is accomplished by selective enabling a sub-array of photosensitive elements with the electromagnetic radiation sensor.

Abstract: The present disclosure relates to a method of laser safety verification for a depth map sensor, comprising illuminating, during a first illumination phase, using a laser illumination system, a first cluster of one or more first pixels of a pixel array of the depth map sensor, while not illuminating a second cluster, different from the first cluster, of one or more second pixels of the pixel array of the depth map sensor; and detecting, during the first illumination phase, a level of illumination of the second cluster.

Abstract: Disclosed herein is an optical module including a substrate, with an optical detector, laser emitter, and support structure being carried by the substrate. An optical layer includes a fixed portion carried by the support structure, a movable portion affixed between opposite sides of the fixed portion by a spring structure, and a lens system carried by the movable portion. The movable portion has at least one opening defined therein across which the lens system extends, with at least one supporting portion extending across the at least one opening to support the lens system. The optical layer further includes a MEMS actuator for in-plane movement of the movable portion with respect to the fixed portion.
