Description
Summary:Since two decades, progresses in Laser velocimetry technics have allowed the latter to become competitive for the investigation of complex acoustic fields. These technics are of particular interest in situations where pressure measurements are not sufficient to entirely describe the acoustic fields, as is the case in nonlinear acoustics. In this paper, performances of Laser Doppler Velocimetry (LDV) and Particle Image Velocimetry (PIV) are presented on the basis of results available in the literature. Then the benefit of these technics for a better understanding of certain nonlinear phenomena are highlighted based.
