Short summary
Air-coupled ultrasound is a non-contact non-destructive testing method. In many cases air-coupled ultrasound is used in a transmission mode requiring access from both sides of the specimen. Air-coupled ultrasound can be used in a re-emission mode enabling single-sided testing. In this work a sensor head with automatically adjustable ultrasound probes was developed to make one-sided air-coupled ultrasound easier. With this integrated sensor head it is possible to detect defects in thin walls.
