Abstract
The application of frequency-modulated continuous waves (FMCW) to the scanning acoustic microscope (SAM) is described. The technique provides a convenient way of separating specimen topography from reflectivity while enjoying the advantages of pulse compression. Furthermore, the system will enable sophisticated signal processing to be carried out at audio frequencies.
