1. A device comprising:
a light emitter configured to emit 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;
a light detector; and
a circuit connected to the light detector, wherein the circuit is configured to:
detect a first signal corresponding to an output of the light detector during the timeframe preceding the light pulse;
detect a second signal corresponding to an output of the light detector during the timeframe following the light pulse;
bias the light detector during a first portion of the pulse period; and
