Abstract

Techniques for determining a phase delay of a received light signal are discussed herein. A vehicle may emit a continuous light signal from a ToF device. The ToF device may include a sensor receiver configured to receive the signal after the signal reflects off surface(s) in the environment. To determine the distance between the ToF device and the surface(s), the vehicle may sample the received signal at two or more offsets and identify regions of overlap between the offset signals and the received signal. The vehicle can determine area measurements of the overlapping regions and use such area measurements to determine normalized amplitudes for each of the overlapping regions and, based on comparing such values, determine linear equation(s) corresponding to the phase delay. The vehicle can evaluate such linear equations to determine the phase delay of the received light signal. The vehicle can be controlled based on the phase delay.
