Paper Abstract

Several work performed at the Fraunhofer Institute IZFP Dresden on photo and particle acoustic methods is presented. It includes both, modeling activities by an explicit numerical method (CEFIT) and experimental work. The given examples of applied excitations are photons (Laser acoustics) and electrons (Scanning Electron Acoustic Microscopy, SEAM). Both, time resolved measurements by pulse excitation as well as monofrequent measurements by periodic excitation together with signal recovery (lock-in technique) are discussed.
