Optical rangefinder surveying
WebFeb 19, 2024 · An optical rangefinder operates in mostly the same way as an ultrasonic rangefinder but it emits and receives optical signals. The sensor transmitter sends out a pulse of optical signals, the receiver measures the reflected radiation, and the internal clock measures the time differences. WebOptical rangefinders have been around since the 19th century and can be relied on to give accurate readings.
