TIME OF FLIGHT: for accurate measurements with light

Time of Flight technology is a technique for measuring time of flight. The principle of time of flight is based on the propagation time of a wave in a medium, to go from a transmitter to a detector (sensor, camera, ...). On the basis of this data, the sensor establishes the distance of this object.

This technology works even when there is little or no light. The time of flight is considered as an "active" imaging technique therefore a technique that relies on the projection of its own light. Therefore, it does not need an external light source to scan its environment. However, the technology is sensitive to strong waves emitted by various light sources (shiny surfaces that reflect light, strong energy source).
