  • Publication number: 20240085558
    Abstract: Disclosed herein are system, method, and computer program product embodiments for adjusting a transmission field-of-view (Tx FoV). For example, the system includes a lidar sensor with a series of emitters. Each emitter is configured to transmit light pulses away from a vehicle along a transmission axis to form a transmission field-of-view (Tx FoV). At least one detector is configured to receive at least a portion of the light pulses that reflect off of an object within a reception field-of-view (Rx FoV) along a reception axis. A transmit optic is mounted for translation along a transverse axis and configured to intersect each transmission axis without intersecting the reception axis to adjust the Tx FoV without adjusting the Rx FoV.
