TOF-Sensors

Time of Flight (ToF) technology is a method used by sensors to determine the distance of an object by emitting modulated near-infrared (or visible) light. The light is reflected when it comes into contact with an object and the sensor calculates the time or phase difference between the emitted and reflected light. This information is then used to calculate the distance of the object being imaged and generate depth information. By combining this with conventional camera photography, a three-dimensional representation of the object's outline can be created, with different colors representing different distances in a topographical map.

SPAD ( Single Photon Avalanche Diode) pixel design a crucial role in TOF(Time-Of-Flight) technology. As a highly sensitive Photon Detector, the SPAD pixel can detect single photons with high timing accuracy, making it a key Component in TOF Sensors. The design of SPAD pixels determines their performance in terms of detection efficiency, temporal resolution and noise level. Therefore, optimizing the SPAD pixel design  is essential for achieving high quality TOF measurements in various applications, such as 3D sensing, industrial automation and autonomous driving.
