Paper Abstract

This study concentrates on using multimode and singlemode fiber in electronic speckle pattern interferometry (ESPI) to measure deformation and nondestructive testing. The advantages and disadvantages of singlemode versus multimode fiber optic components are discussed. Several experiments which research the problems of applying fiber optics to ESPI for measuring displacement, unbonded faults in the carbon/epoxy honeycomb components are introduced. A series of methods were used to achieve good contrast interference fringes. All the experimental results agree well with the theory.
