Patent number: 11965964Abstract: A solid state LIDAR transmitter with matrix-addressable laser drive circuit includes a first electrical bus that provides a first voltage potential to columns of the matrix-addressable laser drive circuit and a second electrical bus that provide a second voltage potential to rows of the matrix-addressable laser drive circuit. A plurality of column switches connects the plurality of columns to the first electrical bus. A plurality of row switches connects the plurality of rows to the second electrical bus. The transmitter includes a plurality of series connected diodes comprising a laser diode in series with another diode, where a respective one of the plurality of series connected diodes is electrically connected between a respective column and row of the matrix-addressable laser drive circuit to form the LIDAR transmitter. At least some of the second diodes increasing an overall reverse breakdown voltage of the series connected diodes.Type: GrantFiled: April 7, 2020Date of Patent: April 23, 2024Assignee: Opsys Tech Ltd.Inventors: Mark J. Donovan, Raphael Harel, Noam Tziony, Mordehai Caspi, Meir Fogel

Publication number: 20220146680Abstract: 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.Type: ApplicationFiled: November 10, 2021Publication date: May 12, 2022Applicant: OPSYS Tech Ltd.Inventors: Mark J.
