Abstract
A method for the detection of hidden flaws close to the surface of the sample is described. The method uses a fused quartz rod coupled to th e sample. The flaw is measured as a variation in the acoustic impedanc e. The experimental detection of hidden flaws in glass and aluminum is demonstrated.
