Abstract The technique of stored-beam (real-time) holographic interferometry combined with high-speed motion-picture photography was used to determine the transient response of a 20 in.-long cantilever beam. A stored-beam hologram of the 20-in. cantilever beam was set up, and the beam was subjected to a transverse impact at the tip. A high-speed motion-picture camera was placed behind the hologram to record the resulting motion of the interference fringes caused by the impact. The data contained on the movie film were reduced frame-by-frame yielding the displacement—time history of several stations along the length of the beam. A description of the experimental setup, test procedure, data-reduction process, and a comparison of the experimental results with the theoretical displacement—time history are presented. The results showed generally good agreement between theory and experiment.
