This article describes a method for combining information from two or more acoustic micrographs of the same object (and the same field of view) but taken at different focal positions, into a single composite micrograph containing all of the information of the separate micrographs. Since the typical acoustic lens has high numerical aperture, the depth of focus is shallow. If a series of acoustic micrographs is taken at different depths, each micrograph will contain information primarily from that depth. By coding each of three such micrographs in the primary colors red, green and blue, a false-color composite is obtained.
