Underwater visualization of multi-input interleaved multisinewave fronts for ultrasonic testing of bones specimens usingLaser Doppler Vibrometry

摘要

The interaction of Ultrasound waves with bone material has always been of great interest for the scientificcommunity. This is due to the fact that ultrasonic waves are non-ionizing, cheap, and easy to generate andto detect. The use of multi-input interleaved multisine offers new applications for ultrasonic testing in bonespecimens, where identification of material properties by means of ultrasound pulses often suffers from poor S/Nratio. The research reported here, describes a novel application a of scanning Laser Doppler Vibrometer (LDV)to the analysis of bone specimens by means of underwater visualization of multisines acoustic fields. The resultsdemonstrate that this new non-invasive acoustic measurement technique can successfully visualize and measurereflected acoustic fields, as well as diffraction effects.
