ABSTRACT:
A high energy imaging system provides a "slotted" or "slot-shaped" or "rectangular cross-section" beam of illumination to intercept an annular region of an object of revolution as it is rotated. A detector array is located to intercept the illumination beam emanating from the object. The detector array includes an opto-electric transducer imaging a plurality of scintillating optical fiber or fiber bundles. The optical fiber or fiber bundles are located substantially parallel to each other with longitudinal axes substantially perpendicular to the direction of the illuminating radiation and parallel to the longitudinal axis of the object being imaged.
