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, Sensori 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:
- Emissione laser – The sensor emits a pulse or continuous wave of laser light.
- Riflessione – The laser light reflects off the target surface.
- Calcolo – 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.
Key Advantages of Laser Time of Flight Sensors
- Alta precisione – Millimeter-level precision over distances up to hundreds of meters.
- Misura senza contatto – Ideal for fragile, moving, or hard-to-reach targets.

Domande frequenti (FAQ)
1. What is the difference between a laser time of flight sensor and a LiDAR sensor?
A laser time of flight sensor measures single-point distances, while LiDAR typically uses multiple ToF sensors in a scanning system to generate 3D maps. For LiDAR alternatives, see our optical distance sensors.
2. Can a laser time of flight sensor work outdoors?
Yes. Many modern laser ToF sensors are designed with strong signal processing, making them suitable for outdoor use even in bright sunlight.
3. What is the maximum range of a laser time of flight sensor?
Depending on the model, ranges vary from a few centimeters to over 3000 meters. Industrial-grade sensors can achieve long-distance precision with stable performance.
4. How accurate is a laser time of flight sensor?
Accuracy can reach ±1–3 mm in controlled conditions, which is why these sensors are widely adopted in applications requiring high precision.
5. Is a laser time of flight sensor better than an ultrasonic sensor?
Yes, in most industrial scenarios. While ultrasonic sensors are cheaper, laser ToF sensors offer faster response, longer range, and much higher accuracy.
6. What industries use laser time of flight sensors the most?
They are common in robotics, logistica automation, drones, surveying, costruzione, and automotive safety systems.
The laser time of flight sensor is one of the most reliable and versatile technologies for distance measurement today. Its combination of accuracy, speed, and adaptability makes it a key enabler in robotics, industrial automation, surveying, and smart technologies.
