Abstract
The interaction of Ultrasound Waves with bone material has always been of great interest for the scientific community. This is due to the fact that ultrasonic Waves are non-ionizing, cheap, and easy to generate and to detect. The use of multi-input interleaved multisine offers new applications for ultrasonic testing in bone specimens, where identification of material properties by means of ultrasound pulses often suffers from poor S/N ratio. 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 results demonstrate that this new non-invasive acoustic measurement technique can successfully visualize and measure reflected acoustic fields, as Well as diffraction effects.
