|Abstract: ||Analysis of acoustic wavefronts are important for a number of engineering design, communication and healthrelated
reasons, and it is very desirable to be able to understand the interaction of acoustic fields and energy
with obstructions. Experimental analysis of acoustic wavefronts in water has traditionally been completed with single
or arrays of piezoelectric or magnetostrictive transducers or hydrophones. These have been very successful, but the
presence of transducers within the acoustic region can in some circumstances be undesirable. The research reported
here, describes the novel application of scanning laser Doppler vibrometry to the analysis of underwater acoustic
wavefronts, impinging on circular cross section obstructions. The results demonstrate that this new non-invasive
acoustics measurement technique can successfully visualise and measure reflected acoustic fields, diffraction and refraction
