Tracking: Identifying with high precision the temporal signature of different events allows for their association and it reduces random coincidences. Traditional tracking is often overwhelmed by combinatorial backgrounds, which can be severely reduced by adding a 4th dimension per point.

Time of Flight (ToF): ToF is already used in many commercial applications such as ToF-enhanced PET and Mass Spectroscopy ToF, however with precision more than one order of magnitude higher than the goal of UFSD (~500 picoseconds vs. ~50 picoseconds). ToF is also used in particle physics as a tool for particle identification.

3D and Robotic Vision: The ability to accurately measure the travel time of light pulses reflected by an object at unknown distance is of paramount importance to reconstruct 3D images, fundamental in imaging and robotic vision. UFSD will offer a spatial precision of a few mm, revolutionizing the current applications.

Particle counting: UFSD performance would allow developing new tools in single particle counting applications with unprecedented rate capabilities. For example, in the treatment of cancer using hadron beams, such a tool would measure the delivered dose to patients by directly counting the number of hadrons. Material science experiments using soft x-rays will benefit from the combination of high rate and precision location that UFSD offers.
