A method and system for automatically and simultaneously measuring the light output of multiple scintillators, or each scintillating unit of an array, were developed. Using a large area flat panel PSPMT H8500, the light output and energy resolution were obtained automatically by comparing with reference scintillators or array using an Energy Table, Look-up Table and energy spectrum data. The aim of developing an efficient performance evaluation of scintillators was achieved. Using the method, a scintillator performance testing system was set up and six LYSO crystals and a 3×3 LYSO array were measured. The results showed that the light output and energy resolution were accurately measured automatically. The deviation of repeat measurements for the same sample was not more than 2%, and the nonlinear deviation of the system was not more than 3%. The system is suitable for measuring the performance of crystals, especially where the mass measurement of crystals and arrays is required.
