1. A method comprising:

  • causing a signal emitter to emit a signal during a first period of time;

    receiving, at a signal receiver comprising a photodiode, a reflected signal during a second period of time, wherein the received reflected signal corresponds to the emitted signal, and wherein the second period of time begins after a beginning of the first period of time; and

    increasing a signal gain that is applied to the received reflected signal during a third period of time, wherein increasing the signal gain comprises increasing an operating voltage of the photodiode according to a predefined function of time, and wherein the third period of time begins not earlier than a beginning of the second period of time.
