摘要：

A limited-scan backscatter technique for detecting hidden corrosion and other flaws in aircraft has been demonstrated. Both simulation and experimental results indicate that as little as 5% material loss at depths up to 0.508 cm (0.200 in.) and 10% material loss at depths up to 0.635 cm (0.250 in.) beneath aircraft skin surfaces can be realiably detected. The technology involves analysis of backscattered photon data to yield a figure-of-merit whose value as a function of position indicates with high probability of detection whether or not flaws - such as corrosion, disbonding, macro-cracks, or voids - exist within scanned samples.
