Fundamentals of Spatio-Temporal Fourier Spectroscopy in Quantitative Acoustic Microscopy
Recently many methods have been proposed in acoustic microscopy for quantitative material characterization  — . In typical measurement scheme, the output voltage of the transducer is recorded as a function of time and relative position of the transducer and the specimen. The velocity and attenuation of the leaky surface acoustic waves and the reflectance function for the immersion liquid—specimen interface can be obtained from the recorded data.
