Optical-interface patterning for radiation detector crystals

摘要: A radiation detector is disclosed that includes a scintillation crystal and plurality of photodetectors positioned to detect low-energy photons generated within the crystal. The crystals are processed using subsurface laser engraving generate point-like defects alter path photons. In one embodiment, define boundaries monolithic delineate individual elements. another depth-of-interaction boundary varies longitudinally vary amount light shared by neighboring portions embodiment evenly distributed reduce lateral spread from event. Two or more these different aspects may be combined in single Additionally, alternatively, similar SSLE produced other light-guiding elements detector.
