Abstract: In certain embodiments, a system for detecting a peak laser pulse includes a laser, a photodiode configured to detect pulses emitted by the laser, and circuitry for detecting a peak pulse timing of the laser. The circuitry is configured to receive a periodic series of voltage signals based on laser pulses detected by the photodiode, stretch the voltage signals, and obtain sampled voltages from the stretched voltage signals using periodic control signals. The circuitry is further configured to shift the timing of the periodic control signals, compare the sampled voltages for respective timings of the control signals, and select an optimal control signal timing based on the comparison.
