Title: PROCESS AND A DEVICE FOR IMPROVEMENT OF OPERATION OF SILICON PHOTOMULTIPLIERS IN THE REGIME OF PILED-UP PULSES OF LIGHT
Abstract:
The present invention belongs to the field of silicon photomultipliers based sensor systems, more precisely to the field of processes for extending the usability of sensor systems with silicon photomultipliers in the regime of piled-up pulses of light and devices, which are based on these processes. The extension of the silicon photomultiplier performance into the piled-up regime is made by adding an intermediate step into the measurement of the incident light intensity. This step takes into account the properties of the sensor and dynamically compensates for the gain loss due to temporary inhibition of parts of sensor. On the basis of this estimation the system reports numerically modified estimations for brightness of flashes.
