Abstract :
Describes how the scanning acoustic microscope may be operated in a continuous wave mode. By oscillating the sample by approximately a few hundred angstroms, single frequency amplitude and phase measurements may be obtained with the acoustic microscope. The method should allow very high frequency quantitative operation of the microscope, where conventional pulse echo methods would fail. A system implementation and preliminary results are presented
