What Is a TOF Laser Range Sensor?
A TOF laser range sensor (비행 시간 레이저 거리 센서) measures the time it takes for a laser beam to travel to a target and return. By calculating that time interval, the sensor can determine the distance with millimeter-level precision — instantly and without contact.
This principle makes TOF sensors ideal for high-speed, high-accuracy 거리 측정 in automation, robotics, and 측량.
