Abstract
When harmonics are produced in the scanning acoustic microscope, the resultant images have a complex appearance which requires interpretation. A theoretical calculation of the distribution of harmonic radiation has been made for the case of a focused beam scanning across the edge of an object such as a Mylar sheet suspended in water. The results show that most of the harmonic signal is generated in the water, and that diffraction causes the appearance of fringes in the image. Experimental results agree with the theory.This publication has 2 references indexed in Scilit:
