Direct time-of-flight sensors (dToF)

Low-power time-of-flight sensing technology from ams OSRAM enables host systems to measure distances accurately and at extreme speed. 

Direct time-of-flight (dToF) sensors ​

ams OSRAM direct time-of-flight (dToF) sensors offer fast, precise distance measurement up to 5 meters, in a compact fully integrated module. Available in both single and multi-zone configurations, these devices provide solutions for a wide range of distance measurement applications including Laser Detect Auto Focus (LDAF) for mobile, human presence detection for enhanced security and power saving in computing, electronic locks & authentication systems and obstacle detection and collision avoidance for home and industrial robots. ​

ams OSRAM direct time-of-flight (dToF) sensors are based on proprietary SPAD (Single Photon Avalanche Photodiode) pixel design and time-to-digital converters (TDCs) which have an extremely narrow pulse width. They measure in real time the direct time-of-flight (dToF) of a 940nm VCSEL Vertical Cavity Surface Emitting Laser) emitter’s infrared ray reflected from an object.  ​

ams OSRAM direct time-of-flight (dToF) technology for world-facing mobile and XR wearables aims to achieve higher range and lower power consumption than other implementations. To minimize integration effort for mobile device OEMs, our 3D dToF system provides a complete technology stack – from optical sensing through to scene reconstruction and integration with RGB camera.​
