Abstract
A method may include modulating a property of a laser with a reference signal to generate a transmit signal, and diverging the transmit signal to illuminate a field of illumination with the transmit signal, wherein the field of illumination includes an object. The method may include receiving, at a sensor, a signal reflected from the field of illumination and the object and comparing a phase of the received signal to a phase the reference signal. The method may include calculating a distance to the object based on the comparing.
