Abstract: A method is for evaluating a coverage factor of a photon emission cone of a time of flight sensor. The method may include the steps of assigning a reference curve to the sensory providing a photon flux intensity as a function of time of flight; and acquiring a time of flight and a corresponding flux intensity with the sensor. The method may also include reading the intensity provided by the reference curve for the acquired time of flight, and providing an indication of the coverage factor based on the ratio between the acquired intensity and the read intensity.
