Abstract

This paper deals with the output signals of scanning acoustic microscopes observing the elastic discontinuities on sample surface, and presents a new method of calculation. The formulation is based on the angular-spectrum method together with a ray-optical approximation. The key treatment is splitting of the pupil function into two parts. This method clarifies the image-forming factors in acoustic microscopy including large and fine fringes parallel to discontinuities. Calculation for an edge and a metal/ceramic joint showed good agreements with the experimental results.
