LIDAR SYSTEM AND METHOD EMPLOYING LATE-LOCK GEIGER MODE DETECTION

摘要

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.
