Abstract
Double exposure, pulsed holography has several inherent advantages as a tool for the vibration analysis of large vehicle components. Since the laser is pulsed at a relatively rapid repetition rate, the time period between the two pulses is sufficiently fast that the holographic system does not need to be isolated from the vibration background of the laboratory. The recent development of pulsed ruby lasers with large energy outputs and long temporal coherence lengths has made the holographic analysis of large vehicle structures feasible and within the state-of-the-art.
