METHOD FOR CONTROLLING THE GAIN AND ZERO OF A MULTI-PIXEL PHOTON COUNTER DEVICE, AND LIGHT-MEASURING SYSTEM IMPLEMENTING SAID METHOD

摘要

A method for controlling the gain and zero of a multiple pixel photon counter device, and light-measuring system implementing said method.;Signals provided by the device are acquired for predefined periods, until a predefined total measurement time is reached, an amplitude histogram is formed from the acquired signals, the positions of two consecutive peaks, measurable on the histogram, are determined, an error signal is produced, which is equal to the deviation between both peaks and, by means of the same, the voltage supplying the device is regulated, so as to keep the deviation equal to a predefined set point.
