Abstract
A method including emitting, by an emitting device of an optical ranging system at a first time, a first light pulse; increasing, after the first time, a sensitivity of a photodetector of the optical ranging system from a first sensitivity at a second time to a second sensitivity at a third time; decreasing, after the third time, the sensitivity of the photodetector of the optical ranging system from the second sensitivity to the first sensitivity at a fourth time, wherein the fourth time is after the photodetector receives a return light based on the first light pulse; and emitting, by the optical ranging system at a fifth time after the fourth time, a second light pulse.
