Abstract: An apparatus includes an optical scanner including a reflective surface and a rear surface, where the optical scanner is mounted to rotate about a scanner. The apparatus includes a control system operatively coupled to the optical scanner. The apparatus includes a motor, operatively coupled to the control system, mounted in proximity to the optical scanner and having a shaft coupled to the optical scanner. The shaft rotates about a shaft axis parallel to the scanner axis causing the optical scanner to rotate about the scanner axis responsively to rotation of the shaft. The motor rotates the optical scanner to each of a set of positions at a respective time based on instructions from the control system. The apparatus includes an optical beam source, operatively coupled to the control system, positioned behind the optical scanner and configured to transmit an optical beam toward the optical scanner while the motor rotates.

The second layer comprises the optical components including an LO to general an LO signal, and a receiver to mix a target return signal and the LO signal to extract at least one of range or velocity information related to the target.

Abstract: A system and method receive a first beam pattern from an optical source that includes optical beams transmitted towards a target. The system and method measure a first vertical angle between at least two of the optical beams along a first axis relative to the FMCW LIDAR system. The system and method calculate a second beam pattern based on the first vertical angle and a pivot point. The second beam pattern produces a second vertical angle between the two optical beams.

A trajectory of the fourth adjusted beam traverses the third side of the plurality of sides to exit the multi-sided scanner to produce a second FOV portion.

Abstract: Aspects of the present disclosure provide light detection and ranging (LIDAR) systems and methods for changing or adjusting field of view (FOV) during operation. Changing the FOV may include transmitting an optical beam toward a target, and forming the FOV using the optical beam via a first rotating reflector and a second rotating reflector. The first rotating reflector may include a galvo mirror in control of the vertical FOV, and the second rotating reflector may include a rotating polygon mirror in control of and providing for the horizontal FOV. The FOV may be adjusted in the vertical direction by actuating the first rotating reflector along a vertical direction using a first actuator. The first actuator may determine the actuation based on an orientation of the LIDAR system (e.g., a difference between an initial orientation measured after installation and a baseline orientation referencing a horizontal orientation).
