Abstract

An ultrasound system for investigating the integrity of a bonded joint between a panel and a supporting structure, for example a vehicle glazing panel and a supporting frame, is disclosed. An ultrasonic transmitter is used to produce an ultrasonic transmission signal and a hand held, hand manipulable ultrasonic receiver is used to pick up the ultrasonic transmission signals and produce an output. The ultrasound transmission signal is modulated with a square wave form envelope in order to most effectively filter out background noise; and/or the receiver includes an adjustable gain control providing continuously variable gain over a predetermined range.
