Titel
Grain-size measurements by spectral evaluation of line-scans in scanning acoustic microscopy

Korngrößenbestimmung durch spektrale Auswertung von Zeilenabtastungen des akustischen Reflexionsrastermikroskops
Abstract
The contrast mechanism of the Scanning Acoustic Microscope (SAM) allows for an excellent imaging of grain structures. We used line-scans over polycrystalline samples obtained with SAM to deduce the grain size of the material. We applied two spectral evaluation techniques: power spectrum and cepstrum analysis.
