A portable thermosonic inspection system has been developed incorporating a miniature microbolometer array camera. The vibrations excited during a test are monitored using a high frequency microphone and assessed automatically to validate the test. An investigation of the correlation between thermosonic heating and vibration excitation energy in composites is presented. The system has been trialled on aerospace components containing impact damage.
