Holographic imaging of cylindrical ultrasonic waves

This report is devoted to the visualisation of standing cylindrical ultrasonic wave, generated
by a radially vibrating piezoelectric shell, by means of time-average holographic interferometry.
The theoretical basis of this technique was introduced, and the expression of light
intensity distribution during holographic reconstruction of cylindrical waves was presented.
Finally, the theory was verified by experimental findings. Quite a good agreement between
theoretical predictions and experimental results was found.
