Optical fiber characterization for its implementation in speckle pattern interferometry

Abstract

Speckle interferometry is a powerful and basic technique to test mechanical parameter. Traditional speckle interferometry is implemented in laboratory, with bulk components. On the other hand, real applications demands of more practical set-ups: compact and robust. Optical fibers present a possibility to substitute some bulk components and to access far and adverse mediums. Based on our experimental experience we discuss the advantages and disadvantages in the implementation of optical fiber in speckle interferometry. In order to observe high constrast of fringes; we tested different and conventional fiber. We compare results from different types of fibers and discussed the viability to implement it in optical speckle interferometry.
