Abstract The use of scanning laser-vibrometry for the investigation of various phenomena of Lamb wave propagation and interaction for structural health monitoring purposes in CFRP-structures is presented. Different measuring modes and data processing are introduced to characterise piezoactuators and their wave fields, measure velocity dispersion and direction-dependent attenuation and describe the interactions with defects.
