Abstract
Disclosed are improved LiDAR systems methods employing late-lock Geiger mode detection. In sharp contrast to the prior art, a late-lock Geiger mode detection system and/or method utilizes a pulsed laser and asynchronous avalanche photodiodes with a holdoff time between photodiode arm pulses that are substantially equal to—but slightly less than—the laser pulse period. Preferably, such difference between the holdoff time and the pulse period is <10 nsec.
