Abstract
Nesch, LLC will evaluate an in-laboratory Diffraction Enhanced Imaging (DEI) and Multiple Image Radiography, here referred to as DEI, machine as a potential new non-destructive evaluation/testing technique for use by the U.S. Army. Unlike conventional x-radiography, which derives contrast only from a specimen's absorption effects, DEI derives contrast from all interactions of X-rays with a specimen (absorption, refraction, and scattering). From a single experiment, DEI can produce a set of images with higher contrast and resolution than conventional radiography. Consequently, DEI provides useful imaging contrast from materials, defects and embedded objects that have very slight differences in x-ray absorptivity. In this feasibility study, the ability of DEI to detect and measure the sizes of flaws, cracks, and inclusions in carbon based materials and to visualize and quantitate corrosion in an aluminum alloy will be investigated. This work will be extended during the Option Period to inspect specimens with more relevance to the U.S. Army. In Phase II the DEI machine's capabilities will be improved and at least one prototype will be delivered that can safely inspect Army tactical weapons systems and identify performance limiting defects without false positives.
