Abstract: An optoelectronic device includes a mount, which is configured to rotate about a rotational axis. A line radiation source is attached to the mount and configured to project a line of radiation onto a scene surrounding the mount as the mount rotates. An imaging assembly is attached to the mount in a location that is offset from the radiation source and includes a temporal contrast sensor including a two-dimensional array of sensing elements, which independently and asynchronously generate event signals in response to temporal changes of irradiance, and objective optics, which are configured to image the scene onto the array.
