Taking flight with accurate distance measurement

There are more and more applications requiring more precise proximity detection, object detection, presence detection and distance measurement. This has in turn increased the demand for better Time-of-Flight sensors. Together with its partners, Avnet brings you a true direct low power ToF sensor system that uses highly sensitive SPAD detection to measure distances accurately at very high speed. A sub-nanosecond light pulse also provides highly exact depth detection. 

Accurate distance measurement from multiple objects is further enhanced by the on-chip histogram processing which cancels out any effect of the cover glass while the on-chip sunlight rejection filter also minimizes background light noise. All distance information can be easily seen on the OLED display. And all algorithms are included on-chip in a single modular package, the smallest in the industry, making system designs fast and simple.
