Paper Abstract

Laser based interferometric techniques find many applications in spacecraft component testing. Holographic Interferometry and electronic speckle interferometry are two such laser based interferometric techniques that are used at our Laboratory for non-destructive evaluation of spacecraft components like honeycomb sandwich panels and propellant tanks. An overview of these techniques, optical setups and applications for various spacecraft components are presented.
