Claim 11:
12. A method comprising:
emitting, by a light emitter, a light pulse during a pulse period, wherein the pulse period includes a timeframe preceding the light pulse and a timeframe following the light pulse;
detecting, by a circuit connected to a light detector, a first signal corresponding to an output of the light detector during the timeframe preceding the light pulse;
detecting, by the circuit, a second signal corresponding to an output of the light detector during the timeframe following the light pulse;
biasing, by the circuit, the light detector during a first portion of the pulse period; and
debiasing, by the circuit, the light detector during a second portion of the pulse period, wherein the light pulse is emitted during the second portion of the pulse period, and wherein the first portion of the pulse period includes the timeframe preceding the light pulse and the timeframe following the light pulse.
