1. A method comprising:
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 to a second sensitivity;
decreasing the sensitivity of the photodetector of the optical ranging system from the second sensitivity to the first sensitivity after the photodetector receives a return light based on the first light pulse; and
emitting, by the optical ranging system a second light pulse after decreasing the sensitivity of the photodetector of the optical ranging system to the first sensitivity.
