Time of Flight. The simplest way to think about âtime of flightâ laser scanning is to look approach it as nothing more than a laser range finder. I think we all understand how a laser range finder works. It basically measures a distance by shooting a laser beam out to an object and measuring how long it takes that laser beam to bounce back.
LiDAR is an acronym of Light Detection and Ranging How does LiDAR work? LiDAR works in a similar way to Radar and Sonar yet uses light waves from a laser, instead of radio or sound waves. A LiDAR system calculates how long it takes for the light to hit an object or surface and reflect back to the scanner.
