- - X- X-Ray Inspection using Wavelength-Shifting Fiber-Coupled Scintillation Detectors

摘要

The present invention relates to detectors and methods for inspecting materials based on scintillators coupled to one or more photodetectors by wavelength-shifted optical fibers, by temporal integration of photodetector signals. The energy of the transmitted radiation incident on the non-pixelated volume of the scintillation medium is converted into scintillation light extracted from the scintillation light extraction region by a plurality of optical waveguides. These geometrical features thus far provide an efficient and compact detector that enables geometrical features that are not obtainable for backscattering detection and energy fractionation of incident radiation. Additional energy decomposition transmission configurations are possible as distortion and misalignment compensation.
