Abstract

The invention relates to a scintillation crystal radiation detector with a special light emitting surface matched with a lens group. A matched wide-angle and large-depth-of-field lens group is constructed, so the collection efficiency of the optical sensor on the scintillation light is improved and the energy resolution is improved. The specific parameter design considers the matching with the emergent wave band of the scintillation crystal, so the incident light sensor for focusing and collecting the scintillation light can be increased, the energy resolution is improved, the shape of the light emitting surface of the scintillation crystal matched with the lens group is correspondingly designed, the measurement efficiency and the measurement precision are further improved, and the detection performance can be further improved especially when a high-performance detector is developed.
