How a time-of-flight camera sensor works

ToF sensors are sensors that measure the time of flight of a light beam. Specifically, this means:

  • A light pulse is emitted, usually with a laser.
  • The target object reflects this light beam and directs it back to the sensor.
  • The distance can be calculated based on the time of flight.

Modern ToF sensors use this principle to guarantee complex distance measurements. This allows the field of view of the distance sensor to be divided into several zones. In addition, a high-quality time-of-flight camera sensor can detect several objects simultaneously.

Time-of-flight sensors are shaping the future: autonomous driving & robotics

ToF technology provides valuable services in numerous applications. The range is huge, examples are:

  • Autonomous driving: Distance sensors detect objects and capture them in detail. On this basis, the type of object, the distance and the movement can be determined, among other things.
  • Monitoring systems: With a ToF camera, systems correctly classify moving objects such as people, animals and others.
  • Robots: In the field of robotics, ToF sensors also expand the possibilities. Precise object detection is an essential prerequisite for optimising the functionality of this technology.

Buy ToF sensors in industrial quality

At EXPtech, you can order ToF sensors from leading suppliers. These include sensors from the US brand Pololu, which are characterised by a compact design and high measurement precision. Choose from an exclusive selection of ToF sensors that differ in terms of their:

  • minimum and maximum range
  • field of view
  • extras such as subdivision into several detection zones and multi-target detection
  • Interfaces

The range and size of the field of view are among the most important criteria. The advantage of the Pololu product range is the wide bandwidth. For example, you can buy a ToF sensor with a range of 4 m!

Frequently asked questions about ToF sensors

Here we answer frequently asked questions about ToF sensors. If you have any further questions or need advice, please feel free to contact us at any time using our contact form.

How does a time-of-flight sensor work?

ToF sensors use the principle of time-of-flight measurement: How long does it take for a light beam to travel from the point of emission to the point of reflection and finally to the point of reception? This makes it possible to calculate the distance between the points.

What is the difference between ToF and LIDAR?

LIDAR stands for Light Detection and Ranging and describes a method for optical distance and speed measurement. The term Time of Flight, on the other hand, refers to the calculation method for distances. These designations are not mutually exclusive; for example, ToF-LIDAR sensors exist.

Which ToF sensor is suitable for which application?

One important criterion is the minimum and maximum range of the ToF sensor. The size of the field of view is also important. All performance data must correspond to the desired purpose.
