  • Photosensor testing apparatus, a radiation detection apparatus including a photosensor and a method of selecting the photosensor for the radiation detection apparatus
    Patent number: 9024265
    Abstract: A photosensor testing apparatus can be used to test photosensors. A light module can produce simulating light that corresponds to scintillating light of a scintillator or a derivative of the scintillating light. A photosensor under test can produce an output that can be analyzed. A particular photosensor can be determined to have a higher quantum efficiency, a higher signal-to-noise ratio, or another performance criterion and selected for use in a radiation detection apparatus having the scintillator that can produce the scintillating light. The photosensor testing apparatus can provide a more accurate way of selecting a photosensor as compared to only analyzing an emission spectrum and data sheets and other information for the photosensors under consideration.
