Hologram interferometry as a tool to investigate transient waves inmechanics

摘要

Hologram interferometry is a very competitive tool for the studyof transient events like the propagation of bending waves in plates andshells, to visualize shock waves in phase objects like air or water orjust to record double exposure holograms of modes of vibration inoptical modal analysis. A number of experiments to visualize wavepropagation in solids and liquids are presented
