Abstract

A fiber speckle-hologram is formed by two coherent light fields, in which a speckle field emerging from a multimode fiber combines with a convergent reference beam. When the speckle-hologram is illuminated by the same speckle field from the fiber, a high intensity correlation peak is reconstructed. If the fiber is subjected to some status changes, the correlation peak gradually decreases and disappears. The main objective of this paper is to use a `core-ring-intensity-ratio' technique to analyze the correlation peak so the fiber status changes can be determined. An experimental demonstration to confirm this relationship is also given.
