Abstract
An apparatus for non-destructive ultrasonic testing is disclosed that permits focused immersion measurements to be accomplished in a non-immersion, contact mode. The apparatus includes an adaptor for acoustically coupling an elastomeric body to a focused ultrasonic transducer via an acoustic couplant. The adaptor includes a housing for receiving the elastomeric body on one end, and the ultrasonic transducer on another end. A cavity is defined within the housing for receiving a liquid medium that acoustically couples the ultrasonic transducer to the elastomeric body. The elastomeric body has a frontal surface disposed at a face slant angle relative to a longitudinal axis, where the face slant angle can be optimized for the test material. The volume of the housing cavity may be adjusted so as to vary the focal length of the ultrasonic transducer.
