Abstract:
1. An X-ray detector system comprising: an X-ray source, a scintillating material layer, a fiber optic face plate block, and an image sensor array; wherein the scintillating material layer is placed on a first surface of the fiber optic face plate block, a second surface of the fiber optic face plate block is attached to the image sensor array, the fiber optic face plate block being perpendicular to a top surface of the image sensor array, and when a test specimen is exposed to an X-ray beam from the X-ray source, the X-ray beam passes through the test specimen and excites the scintillating material layer proportionally to an X-ray density pattern of the test specimen, a converted optical image from the scintillating material layer is transferred by the fiber optic face plate block onto the image sensor array, a reproduced image of the test specimen thereafter being read out of the image sensor array, and an optical path including the fiber optic face plate block and the image sensor array is offset by an angle less than forty-five degrees relative to a centerline of an X-ray flux path from the X-ray source, such that the image sensor array and analog front-end circuit board electrical components included in the image sensor array are removed from the X-ray flux path.
