What Is a Laser Time of Flight Sensor?
A laser time of flight sensor measures distance by calculating the time it takes for a laser beam to travel to an object and back. This principle, known as “time of flight” (ToF), allows for highly accurate measurements over both short and long ranges.
Unlike traditional optical or ultrasonic sensors, Czujniki ToF provide stable results in challenging environments, such as outdoor lighting or dusty conditions. For applications requiring continuous high-speed performance, explore our high-frequency ranging sensors.
How Does a Laser Time of Flight Sensor Work?
The working principle can be simplified into three steps:
- Emisja laserowa – The sensor emits a pulse or continuous wave of laser light.
- Refleksja – The laser light reflects off the target surface.
- Kalkulacja – The sensor calculates the round-trip time of the laser and converts it into distance.
Because the speed of light is constant, this calculation is precise even at long ranges, making laser ToF sensors suitable for demanding applications.
