High performance ToF sensing
Time-of-flight sensors from ams are based on a proprietary SPAD (Single Photon Avalanche Photodiode) pixel design and time-to-digital converters (TDCs) which have an extremely narrow pulse width. They can measure in real time the direct time-of-flight of a VCSEL (laser) emitter’s infrared ray reflected from an object.
This low-power time-of-flight sensing technology from ams enables host systems to measure distances accurately and at very high speed. Accurate distance measurements are used in various applications including presence detection, user face recognition and advanced cameras.
