Dual energy radiography : a potential corrosion detection technique / by J.D. Leblanc and R.D. Finlayson. : DR52-11/14-1994E-PDF

"The recent demand for extending the service life of aircraft fleets well beyond the original design life has made the early detection of corrosion in aircraft a major concern. Consequently, many nondestructive techniques to improve corrosion detection are being investigated. One potential method is known as "Dual-Energy" (DE) radiography and is based on the analysis of two digital radiographs taken at different effective energies. [...]. The information collected from the two digital radiographs can then be combined to form a single digital image that can be used to determine an unknown substance or to remove the effect of a particular substance to improve radiographic contrast. In this report the theory and concepts of DE are examined and a number of existing systems are discussed. Finally, the possibility of implementing a DE system at the Defence Research Establishment Pacific is investigated"--Abstract (page iii).
