Abstract

An expression for the output signal of a reflection acoustic microscope corresponding to a spherical object is presented in this paper as spherical function expansion. The character of the image is shown to depend on the focal plane position with respect to spherical objects center. The size of spherical objects image is smaller than a real particle dimension at any focal plane position. Experimental data agree with the theory.
