A method of measuring a distance using a time of flight sensor comprising a substantially transparent cover covering a light emitter and one or more photodetectors. The method comprises emitting a series of pulses of light from the light emitter; and using the one or more photodetectors to obtain a distribution of times at which at least one photodetector of the one or more photodetectors detected photons after each emission of the series of pulses of light. If the distribution of times comprises only a single peak, the method further comprises analysing the single peak to determine if the single peak includes counts of photons reflected from a target. If the single peak includes counts of photons reflected from a target, the method further comprises measuring the separation between a reference time and a point of the single peak.

To provide a light-emitting apparatus capable of suitably controlling light emitted from a light-emitting element. A light-emitting apparatus according to the present disclosure includes: a substrate; a plurality of light-emitting elements which are provided on a side of a first surface of the substrate; and an optical element which is provided on a side of a second surface of the substrate and into which light emitted from the plurality of light-emitting elements is incident, wherein the optical element includes a liquid crystal layer which is configured to function as a lens.

A coherent LIDAR imaging system includes a laser source; an optical splitter/recombiner designed to split the laser radiation into a reference beam and into an object beam and to superpose the reference beam on a reflected object beam reflected by the scene; and an optical imager creating an image of the scene on a detector. The detector includes an array of pixels designed for detecting the reflected object beam and the reference beam which together form a recombined beam having a beat frequency representative of a range of the illuminated scene. The optical splitter/recombiner is configured to form an intermediate image of the reference beam in an intermediate image plane perpendicular to the optical axis.

In a ranging image sensor, each pixel includes an avalanche multiplication region, a charge distribution region, a pair of first charge transfer regions, a pair of second charge transfer regions, a well region, a photogate electrode, a pair of first transfer gate electrodes, and a pair of second transfer gate electrodes.
