Time-of-flight measurements of light can be used to measure the distance to an object. Optical time-of-flight measurement detects when a pulse of light emitted from an object is reflected and sent back. This relies on single-photon avalanche diode (SPAD) arrays, in which each photon that hits a sensor causes an avalanche of electrons. This makes individual photons visible, permitting optical time-of-flight measurements.
For each application, we develop time-of-flight (ToF) image sensors that can determine the position of an object with high precision. Time-of-flight cameras for 3D object recognition work at a high resolution and high recording speed. Light detection and ranging (lidar) technology can be used like radar to provide real-time measurements of the distance to an object and to a certain extent its velocity as well. One application of ToF cameras is in driver assistance systems in the automotive sector. Here, they can record the car’s entire surroundings in 3D, including the motion of pedestrians or moving vehicles. ToF image sensors are also used in robotics for industry 4.0 (human-machine interaction).
