An impact microscope (also called sonicmicroscope) is an instrument that enables characterization of solid samples. Using a hammer that produces an impact on a sample undergoing testing causes sonic vibrations. An FFT oscilloscope or heterodyne instrument (such as a suitable spectrum analyzer) characterizes the vibration fingerprint and stores the data produced by the analytical instrument in order to compare them with other data. Two diamation table is used in order to move the sample under test.
