Assignee: VELODYNE LIDAR USA, INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An integrated light detection and ranging (LIDAR) device, comprising:
an illumination source mounted to a substrate, the illumination source configured to generate a measurement beam of light;
a detector mounted to the substrate, the detector configured to detect a return beam of light and generate an output signal indicative of the detected return beam, wherein the return beam and the measurement beam share a common optical path over a distance within the integrated LIDAR device;
an illumination driver mounted to the substrate, the illumination driver electrically coupled to the illumination source and configured to provide an amount of electrical power to the illumination source to cause the illumination source to emit the measurement beam of light;
a beam splitter mounted to the substrate, the beam splitter configured to separate the return beam of light from the common optical path; and
a collimating optical element located in an optical path of the measurement beam between the illumination source and the beam splitter, the collimating optical element configured to collimate the measurement beam.
