Source: Facebook Understanding Laser Rangefinders Understanding Laser Rangefinders How Laser Rangefinders Work Laser rangefinders often utilize the phase shift method to measure distances. A laser beam with modulated optical power is directed towards a target. The reflected light is monitored, showing a power modulation with the same frequency. By comparing the phase of the modulation […]
