Abstract
A conformable acoustic coupler for ultrasonically testing an article. The upler has an ultrasonic transducer with an active surface which transmits ultrasonic energy pulses to an article to be tested. A sensor receives and measures an ultrasonic echo from the tested article. The article to be tested is acoustically mated to the active surface by a medium of a gelatinous material layer on the active surface and a flexible film on the gelatinous material layer. The combination of the gelatinous material and film conforms to the shape of the article and provide acoustic coupling between the active surface and the article without leaving a residue of the medium on the article.
