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 10nsec.
