Application Of Pulsed Holography And Double Pulsed Electronic Speckle Pattern Interferometry To Large Vibrating Engineering Structures

The development of double pulsed Electronic Speckle Pattern Interferometry (E.S.P.I) to include a frequency doubled YAG laser is compared with the more conventional double pulsed Holographic Interferometry. The value of these techniques is examined for their engineering relevance and how they can be applied to problem solving within industry.
