Time-Of-Flight (TOF) measuring technique relies on the measurement of the round-trip time needed by a light pulse to travel from the measurement system to a target and back again, which has been actively investigated by the SOI research unit since 2002, exploring a number of different techniques.

3D Image Sensors
The first developments in 3D Vision at SOI were done in the framework of the Opto3D project since year 2000, with the development of an intelligent electro-optical sensor for driving scenarios detection and object recognition . Since then, SOI investigated and developed a number of different operating principles for indirect time-of-flight imaging using CMOS technologies, from the simulation and development of the sensing device, to the integrated circuit and 3D camera system.
