FIELD: measurement technology.
SUBSTANCE: invention is based upon conversion of signal of charge being multiple to charge of single-photon pulse to voltage. Converter signal is stored in analog form in preliminary signal processing unit non-depending on value of registered signal. Procedures mentioned above are repeated many times and cyclically and results are summed subsequently. Scale of scale-plate of analog-to-digital converter is chosen in correspondence with statistical parameters of photo-electronic multiplier and analog-to-digital converter. To reduce redundancy of data transmission the analog-to-digital converter is chosen to have non-uniform sampling interval scale.
EFFECT: widened dynamic range; simplified design; cost reduction.
