Direct-Time-of-Flight (dToF)-Sensoren

Die dToF-Sensoren (Direct Time-of-Flight) von ams OSRAM sorgen für eine schnelle und präzise Abstandsmessung über Entfernungen von bis zu 5 Metern in einem kompakten, voll integrierten Modul. Diese Geräte sind sowohl in Einzel- als auch in Multizonen-Konfigurationen erhältlich und eignen sich für eine Vielzahl von Anwendungen im Bereich der Abstandsmessung, darunter Laser Detect Auto Focus (LDAF) für Mobilgeräte, Anwesenheitserkennung für mehr Sicherheit und Energieeinsparung in Computern, elektronischen Schlössern und Authentifizierungssystemen sowie Hinderniserkennung und Kollisionsvermeidung für Heim- und Industrieroboter.

ams OSRAM Direct Time-of-Flight-Sensoren (dToF) basieren auf einem proprietären SPAD-Pixeldesign (Single Photon Avalanche Photodiode) und Zeit-Digital-Wandlern (TDCs) mit extrem schmaler Pulsbreite. Sie messen in Echtzeit die direkte Time-of-Flight (dToF) eines Infrarotstrahls, der von einem 940 nm VCSEL-Emitter (Vertical Cavity Surface Emitting Laser) ausgesendet und von einem Objekt reflektiert wird.

ams TMF8701 1D Time-of-Flight Sensor

The TMF8701 is a true direct time-of-flight (ToF) sensor system in a single modular package which offers highly accurate depth accuracy detection through a sub-nanosecond light pulse and an antialiasing “stop-watch” method to measure round-trip time of pulse. It provides single zone detection of an object irrespective of the color, reflectivity and texture of the object. The single module with VCSEL emitter offers high dynamic range and operates in either a proximity mode (0 – 10 cm) or a ranging mode (10 – 60 cm) for detection sensing. The device utilizes highly sensitive SPAD detection with fast compact time-to digital converters to make high accurate distance measurement within ±5% and is capable of operation in dark environments. A built-in histogram is featured to detect cover glass and objects behind glass to select object with highest SNR while compensating for dirt and smudges on cover glass to produce artifact free measurement of multiple objects. The histogram enables greater distance between cover glass, delivers dynamic cover glass calibration and crosstalk compensation. Class 1 eye safety is also featured through the narrow sub-nanosecond (<500 ps) fast pulse 940 nm VCSEL driver. Background light noise is minimized through on-chip superior sunlight rejection filter. Data output is through a 1.8V I²C fast-mode communications interface and an integrated micro controller is featured with all algorithms included on-chip with no need for external optics. <a href="https://ams-osram.com/news/press-releases/ams-tmf8701-true-direct-time-of-flight-tof-sensor-wins-best-of-sensors-innovation-and-the-company-scores-best-engineering-team-at-sensors-expo-2019" target="">The TMF8701 wins the Innovative Product of the Year Award at Sensors Expo 2019</a>

ams TMF8829 48x32 multi-zone Time-of-Flight sensor

Product status: Pre-Production The TMF8829 is a direct time-of-flight (dToF) sensor with configurable resolution of 8x8, 16x16, 32x32 & 48x32. The device is based on SPAD, TDC, and histogram technology and achieves a detection range of up to 11000 mm with an 80° field of view. All processing of the raw data is performed on-chip, and the TMF8829 provides distance information along with confidence values, signal amplitude, and ambient light on its interface. Internally, the TMF8829 uses dToF histograms and peak detection, and therefore, it is highly tolerant to smudges on the cover glass. Additionally, the TMF8829 can handle multiple objects per depth point simultaneously without degrading accuracy. It reports the distance of all depth points with a resolution of 0.25 mm. The device uses an I3C (I²C compatible) communication interface and a fully featured SPI interface for control and raw data streaming. A VBUS supply pin allows operation of the I²C/I3C or SPI with 1.2V, 1.8V, or 3V I/O supplies. Raw data streaming, including all algorithm peak detection results, allows further processing on the host for “AI-enabled” applications. The TMF8829 is a fully contained optical module measuring only 5.7 mm x 2.9 mm x 1.5 mm.
