Abstract: A two-dimensional VCSEL array may include a VCSEL array including a VCSELs arranged in a two dimensional matrix forming a monolithic structure, a light-emitting surface, and a rear surface, first metal contacts provided on the light-emitting surface; and second metal contacts provided on the rear surface. The VCSELs may be arranged in first lines in a first direction and second lines in a second direction non-parallel to the first direction. Each of the first metal contacts may be electrically connected to each VCSEL of a corresponding first line. Each of the plurality of second metal contacts may be electrically connected to each VCSEL of a corresponding second line. The first metal contacts and second metal contacts may be arranged such that each combination of a first metal contact and a second metal contact is electrically connected to one VSCEL.

Abstract: A method of performing ranging and detection with an array lidar system and the array lidar system include a first illuminator to transmit a first pseudorandom binary sequence of pulses, the first pseudorandom sequence of pulses resulting in first reflections, and a second illuminator to transmit a second pseudorandom sequence of pulses, the second pseudorandom sequence of pulses being transmitted at least partly concurrently with transmission of the first pseudorandom sequence of pulses, the second pseudorandom sequence of pulses resulting in second reflections. A receiver receives the first reflections and the second reflections and associates the first reflections with the first illuminator based on a result of correlating the first reflections with the first pseudorandom sequence of pulses and a result of correlating the first reflections with the second pseudorandom sequence of pulses, the receiver includes an optical detector array and a processor.

Abstract: A method of determining a surface condition of a road of travel. A light beam directed at a surface in the road of travel is transmitted utilizing a lidar system. A response is analyzed at a photodetector of the lidar system after transmitting the light beam. A determination is made whether a form of precipitation is present on the road of travel in response to analyzing the response at the photodetector. A precipitation indicating signal is generated in response to the determination that the ground surface includes a form of precipitation on the road of travel.
