Paper Abstract

Low coherence interferometric systems using multimode fiber link between reference interferometer and sample or (and) between sample and photodetector are studied. The general theory of these systems is developed, and their real world performance in industrial environments is estimated. The hybrid interferometric systems are proposed in whose the sample is illuminated via singlemode fiber, and the light from the sample is delivered to the photodetector via multimode fiber. The advantages of such systems are shown. Possible industrial applications of multimode fiber optical interferometry for in-line measurement of geometric parameters are discussed.
