Difference between lidar and laser scanning
WebJun 22, 2004 · One reason is that in a TOF device, each laser pulse must have time to return to the detector before the next one is sent out. If the signal is making a 2-kilometer round trip, the speed of light would limit the signal rate to 150,000 pulses per second, even before allowing for latency in the detector. WebDec 6, 2024 · Lidar scanning measures distance by illuminating a target with pulses of light just outside the visible spectrum to measure the time it takes for the light to reflect off its surface and return to a sensor.. It works similar to a RADAR system, except the RADAR …
