Abstract

A pulse ruby laser is used to record double exposure holograms of large vibrating military vehicle components. Various methods are described to load the structures using small portable shakers. Several examples are presented which analyze the global fringe patterns of Army vehicles and relate them to the bending waves that are propagated from the track and suspension to the hull and turret. The temporal coherence requirements of the laser are described along with its mechanical and thermal stability for reliable operation in the laboratory.
