Abstract
Modulated light is generated using a light source of a sensor module. Using a photodetector of the sensor module, an intensity of modulated light reflected from an object towards the photo detector is measured over a period of time. An electronic control device bins the measured intensity of the reflected modulated light according to a plurality of temporal bins, determines a first temporal bin having the greatest intensity among the plurality of temporal bins, and estimates a distance between the sensor module and the object based on a first temporal bin, and one or more additional temporal bins of the plurality of temporal bins.
