1. A light detection and ranging (LiDAR) system comprising:
a fiber optic ending comprising a fiber optic cable terminated by a reflector;
a laser assembly that emits a chirp signal to detect an object in an environment, wherein a portion of the chirp signal is diverted to the fiber optic ending; and
one or more processors configured to:
determine a profile of the chirp signal based on the diverted portion of the chirp signal; and
determine a range of the object based on the profile of the chirp signal.
