ABSTRACT:
A radiation damage resistant linear X-ray detector array system based on a unique focusing principle reduces or eliminates the X-ray radiation damage on the electrical components of the detector system. The system includes a layer of scintillating material, a rod lens array, and an array of image sensors. The layer of scintillating material, such as Gd2O2S:Tb (GOS or GADOX), CsI(TI), or CdWO4, is placed on an image plane and used to convert the impinging X-ray energies into visible light which can be detected efficiently by the image sensor array. The rod lens array is used to focus the visible light after the X-ray flux has been converted. The photon energy of the visible light is collected with a scanning image sensor array that converts the photon energy proportionally into electrical video signals and enables the signals to be processed using standard signal and image processing software and equipment.
