Abstract:
1. A radiation detector array comprising: a plurality of scintillation crystals, that emit bursts of light in response to radiation; a plurality of photodetectors, each photodetector having a light sensitive region optically coupled with at least one optical coupling element to a light emitting face of at least one scintillation crystal; a diffuse reflective layer, at least partially enclosing each scintillation crystal, the diffuse reflective layer diffusely reflecting a first portion of the light emitted by the scintillation crystal and incident upon the diffuse reflective layer and passing a second portion of the emitted light; a specular reflective layer, adjacent the first reflective layer such that the first portion of the light that has passed through the diffuse reflective layer back towards the diffuse reflective layer and the scintillation crystal.
