Airscan is a non-contact air-coupled ultrasonic inspection technique which differs from conventional water-immersion testing, water-jet testing and dry-coupled testing by using air as the acoustic coupling media between the transducers and the part under test.
Applications: Airscan is intended for use with engineered materials, such as:
Laminated Materials: Aluminum Laminates, CFRP Lay-ups, FRP Lay-ups, Bonded Assemblies
Core Materials: Honeycomb Core, Foam Core, Balsa
For most practical applications, Airscan is a through-transmission technique, whereby two transducers are used in the process: one transmitter and one receiver. The transducers are located in a fixed relationship to one another with the test piece between them. A very powerful burst of ultrasonic energy is directed by the transmitter toward one surface of the test piece. A small percentage of that energy will pass through the structure and radiate out the opposite side, detectable by the receiver transducer. The degree to which the energy is modified is dependent upon the internal structure of the panel. In the case of a 'good' lamination, a readily detectable signal will be available to the receiver transducer; whereas, in the case of a 'bad' lamination (non-bond, disbond, void, or inclusion) the signal will be further modified.
