Title:Measurement of change of thickness for thin plate by holographic; interferometry

Isopachic Fringes
Abstract:A holo-moire technique capable of compensating for rigid body motion for plane stress problem and providing a full-field isopachic fringe pattern is described. This technique combines holographic interferometry and the moire effect. Double exposure holograms are made from both sides of an object before and after deformation. The two sets of holographic interferometric fringes thus obtained are treated as random grids. Moire of these two grids yields the desired isopachic fringes. The theory is experimentally confirmed with several examples. Limitations of this technique are also discussed.
