Method for signal separation in scintillation detectors

A method for determining a resolution of a light detector, comprising:

• distinguishing effective pulses from test light pulses in a scintillation detector that generates measurement light pulses by:
• providing a regularly-pulsed test light source that produces individual test light pulses each having a time-dependent course of relative light intensity that differs from each time-dependent course of relative light intensity of the effective pulses;
• providing the test light pulses generated by the test light source to the light detector of the scintillation detector for measurement of the test light pulses by the light detector while a scintillator is providing the effective pulses to the light detector for measurement;
• analyzing the time-dependent courses of the relative light intensities of the test light pulses measured by the light detector to determine energy signals of the test light pulses and one or more pulse form parameters of the test light pulses as functions of the determined energy signals;
• and
• separating the measurement light pulses into the test light pulses and the effective pulses according to the different time-dependent courses of the relative light intensities based on the one or more pulse form parameters of the test light pulses;
• analyzing pulse amplitudes of the separated test light pulses at different points in time;
• and
• determining the resolution of the light detector from a dispersion of the pulse amplitudes.
