Abstract
A LIDAR system includes a LIDAR chip configured to combine a LIDAR input signal and a reference signal so as to generate a composite light signal. The LIDAR input signal includes light reflected by an object located off of the LIDAR chip. The reference signal does not include light reflected by the object. The system also includes electronics configured to use the composite light signal to approximate a radial velocity between the LIDAR chip and the object. The radial velocity is approximated from a difference between a first distance and a second distance. The first distance is the distance between the object and the LIDAR chip at a first time. The second distance is the distance between the object and the LIDAR chip at a second time.
