Abstract: A LiDAR transmitter with optical power monitoring includes a laser array positioned in a first plane that generates optical beams that propagate along an optical path. A first projecting optical element positioned in the optical path projects the plurality of optical beams to overlap at a common point. A second projecting optical element projects light from the first projecting optical element in a direction of transmission. A directing optical element positioned at the common point in the optical path of the plurality of beams produces an illumination region with light from each of the plurality of beams in a second plane. A monitor generates a detected signal in response to the collected light. A controller generates the electrical signal in response to the detected signal that controls the laser to achieve a desired operation of the LiDAR system transmitter.

Abstract: A solid state LIDAR transmitter includes a two dimensional array of laser devices having columns and rows and configured such that anodes of laser devices in a column are connected to a common anode connection and cathodes of laser devices in a row are connected to a common cathode connection. A capacitive discharge circuit comprises a first switch configured so the capacitive discharge circuit charges to a voltage potential when the first switch is open and discharges when the first switch is closed. A second switch is configured such that the common cathode connection is coupled to ground when the second switch is closed. A controller is configured to instruct the first switch and the second switch to close at a time t0 such that the capacitive discharge circuit charges to the voltage potential at a time, t1, thereby causing a laser device connected between the capacitive discharge circuit and the second switch to generate an optical pulse.
