Kinematic mount for active receiver alignment with multi-degree-of-freedom

A light detection and ranging (LiDAR) system comprising an optical receiver subsystem, the optical receiver subsystem comprising:

• a carrier frame;
• a lens assembly coupled to the carrier frame, the lens assembly comprising:
• a lens holder detachably mounted on the carrier frame by a first set of elastic connectors attached to the carrier frame and the lens holder;
• and
• a lens installed on the lens holder;
• a first set of screws extending through the carrier frame and in contact with the lens holder, wherein the first set of screws are adjustable to change at least one of a distance or an orientation of the lens holder with respect to the carrier frame;
• and
• a light sensor assembly detachably mounted on the carrier frame and configured to both rotate and linearly move with respect to the carrier frame, the light sensor assembly comprising:
• a board mount;
• a sensor board installed on the board mount;
• a light sensor installed on the sensor board, wherein the first set of screws and the light sensor assembly are adjustable to cause an image to be formed on the light sensor by the lens;
• a hub coupled to the carrier frame, the hub including a first opening, a second opening, and a third opening, wherein the first opening, the second opening, and the third opening each extend in a respective direction in three orthogonal directions;
• a rotate shaft including a first portion in the first opening in the hub and a second portion coupled to the board mount;
• a drive shaft coupled to the rotate shaft through the second opening in the hub, wherein the drive shaft is characterized by a cross-sectional area smaller than a cross-sectional area of the second opening;
• and
• a first adjustable member extending through the third opening in the hub and in contact with the drive shaft, wherein the first adjustable member is adjustable to rotate the drive shaft and the rotate shaft with respect to the hub.
