Abstract
Electronic speckle pattern interferometry (ESPI) based on incoherent multimode fiber-optic bundles (MMBs) and coherent multimode image bundles is considered. Application of MMBs ESPI to measure displacement, strain, and unbonded faults in the carbon/epoxy honeycomb components is experimentally evaluated. It is concluded that the MMBs ESPI method is an extremely powerful tool for analyzing displacement, strain, and nondestructive testing.
