Abstract

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.
