Abstract
An apparatus and method for inspecting multilayer articles. An article to be inspected is clamped in a liquid filled tank between a pair of focused transducers. An ultrasonic pulse is introduced to a cross section of the article from each transducer sequentially. Reflections from the surfaces and interfaces within the article are received by each transducer and transmitted to a computer for analysis. The thicknesses of the innermost layers of the article are determined by calculating the mean of the measurements from each transducer for each inner layer.
