Abstract
The invention relates to a device comprising a photosensitive element producing an electric charge as a function of the radiation incident thereon and a charge integrator connected to the photosensitive element and converting the charge to a voltage. According to the invention, the device comprises a comparator capable of comparing the voltage delivered by the integrator with a threshold voltage, and a memory unit for storing the instant when the voltage delivered by the integrator exceeds the threshold voltage.
