Abstract

An expression is obtained for the output signal of a reflection acoustic microscope during the scanning of a spherical object. It is shown that the nature of the image of such an object depends significantly on the position of the focal plane relative to the centre of curvature of the sphere. The experimental results are in good agreement with theory.
