Abstract
A transducer assembly and a system application wherein said transducer assembly may be used in the inspection of iron, steel, aluminum, as well as plastic materials as a homogeneous object in the form of a sheet, slab or bloom. Inspection is through use of ultrasonic acoustic energy propagated through ambient air. A coupling medium in the form of matching layers efficiently couple the transducer assembly to the ambient air.
