1. A light detection and ranging (LiDAR) system, comprising:
a transmitter system comprising a laser;
a first mirror configured to move according to a first motor motion, wherein the first mirror is configured to control one or more directions of light originating from the laser;
a controller configured to obtain images of at least two dimensions from return light to determine distances of one or more objects in a field of view; and
monitoring circuitry configured to:
monitor the first motor motion for a fault condition associated with the first motor motion;
detect occurrence of the fault condition associated with the first motor motion; and
deactivate the laser in response to a detected fault condition associated with the first motor motion.
