New Technologies for Distance and Movement Tracking,
Featuring STMicroelectronics ToF Sensors

Time-of-Flight (ToF) sensors have an endless variety of uses across many industries. In this episode of The Current, Todd Baker talks to John Kvam about how STMicroelectronics’ ToF sensors provide an all-in-one (emitter, receiver, and processor) system for an easy, cost effective, and small footprint integration.

Explore applications ToF is rapidly growing into, and look in depth at a people counting application system that we can share with customers.

How do Time of Flight (ToF) Sensors work?

There are various types of ToF sensors, but typically, Time of Flight measures how long it takes an object, particle or wave to travel a certain distance, reflecting off an object and returning to the sensor itself.

What is the precision of a Time of Flight Sensor?

This actually depends on the optics, emitter and receiver types, as well as lensing and more. Generally, ToF cameras are able to accurately detect objects in a short distance of approximately 1-2 cm, all the way to many meters. ToF sensing applications are flexible and able to adapt to objects of different shapes and sizes.
