摘要
The Invention refers to an airborne ultrasound testing system for a test object (3) containing an ultrasound generator (1; 9) and an ultrasound receiver (2) and a control to control both and a computer assisted test result interface to display an image of the tested test object (3). The ultrasound generator (1) is a resonance-free thermo-acoustic ultrasound generator which does not rely on mechanically deformable or oscillating parts and the ultrasound receiver (2) is a membrane-free and resonance-free optical microphone in an air or gas coupled pulse echo arrangement or in an air or gas coupled transmission mode arrangement. With this testing system, it is possible to test objects with high precision and without liquids and disturbing ringing effects.
