Claim 1:
2. The device of claim 1, further comprising:
a second counter configured to increment a second count each time a second-counter increment command is received, the second counter being configured to decrement the second count each time a second-counter decrement command is received;
the gate circuit comprises a third state wherein the gate circuit transmits the second-counter increment command to the second counter each time the photon-detection alert is received and the gate circuit comprising a fourth state wherein the gate circuit transmits the second-counter decrement command to the second counter each time the photon-detection alert is received; and
wherein the control signal sets the gate circuit to the third state after passage of a third-state delay that is determined based on the second count and the first count, the third-state delay being measured from the time of the optical-emission time; and
wherein the control signal sets the gate circuit to the fourth state after passage of a fourth-state delay that is determined based on the second count and the first count, the fourth-state delay being measured from the time of the optical-emission time.
