Classification: CPC G  H | IPC G  H

Claim 14:
15. A method of operating an optical sensor, the method comprising:
reverse biasing a first photodetector of the optical sensor above a first breakdown voltage of the first photodetector by a first excess bias voltage;
reverse biasing a second photodetector of the optical sensor above a second breakdown voltage of the second photodetector by a second excess bias voltage, wherein reverse biasing the second photodetector comprises varying the second excess bias voltage from a first value to a second value during a first portion of a shot cycle of a photoemitter of the optical sensor; and
reverse biasing a third photodetector of the optical sensor above a third breakdown voltage of the third photodetector by a third excess bias voltage, the third excess bias voltage being different from the first excess bias voltage and the second excess bias voltage, wherein reverse biasing the third photodetector comprises varying the third excess bias voltage from a third value to a fourth value during a second portion of the shot cycle of the photoemitter.
