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.<br/><br/>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.<br/><br/> 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. <br> <br/><br/><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 TMF8801 1D Time-of-Flight Sensor
|
The TMF8801 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 detection sensing measurements from 2 – 250 cm distances. The device utilizes highly sensitive SPAD detection with fast compact time-to digital converters to make highly accurate distance measurements within ±5% and is capable of operation in dark environments and in the presence of sunlight. A built-in histogram is featured to detect cover glass and reports an object distances operating with the highest SNR while compensating for dirt and smudges contaminants on a products cover glass to produce artifact free measurement. The histogram delivers dynamic cover glass calibration and crosstalk compensation and background light noise is minimized through on-chip sunlight rejection filters. 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.

ams TMF8820 3x3 multi-zone Time-of-Flight Sensor
|
The TMF8820 is a direct time-of-flight (dToF) sensor in a single modular package with associated VCSEL. The dToF device is based on SPAD, TDC and histogram technology and achieves 5000 mm detection range. Due to its lens on the SPAD, it supports 3x3 multizone output data and a wide, dynamically adjustable, field of view. A multi-lens-array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination). All processing of the raw data is performed on-chip and the TMF8820 provides distance information together with confidence values on its I2C interface.

ams TMF8829 48x32 multi-zone Time-of-Flight sensor
|
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. <br><br>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. <br><br>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. <br><br>The TMF8829 is a fully contained optical module measuring only 5.7 mm x 2.9 mm x 1.5 mm.
