Abstract
Characterization of back surface roughness is investigated for specime ns exhibiting corrosion and for prepared samples with milled channels of varying geometry. An area heating source is used initially to provi de one-dimensional heating of the specimen which allows plate thinning , disbonding, or presence of corrosion to be rapidly detected. A focus ed heating source is then used to characterize the suspect regions thr ough the interaction of lateral heat flow with back surface roughness.
