Abstract
A method of producing a high angular resolution collimator implemented in an inspection system for detecting the presence of selected crystalline materials, such as explosives or drugs. The system includes an x-ray source and an array of energy dispersive detectors to sense radiation scattered by the objects being inspected. The collimator includes a bundle of optical fibers bonded together to form a stack of plates having a plurality of microcapillaries therein to pass an x-ray beam therethrough. The method includes the steps of stacking the plates, aligning the plates in registration, and etching an inner core without disrupting registration.
