A scanning laser acoustic microscope that simultaneously produces acoustic and optical images of a specimen has already been described.(1,2,3) This paper reports recent developments regarding improving the resolution and regarding operating the microscope in the “interference” mode. The principle of operation of the acoustic microscope is based upon optically measuring the localized dynamic displacements of a mirrored surface which are caused by incident sound waves that are scattered from an object.(4) For further details concerning the basic instrument the reader is referred to the literature cited above.
