Abstract

When a low coherence light source is used in a multimode fiber linked interferometer, the level of the modal noise induced by the environmental perturbations on the fibers may be dramatically suppressed, provide the value of the coherence length, Lc, of the light source employed is less than that of the optical path differences (OPD) between the guided modes at the far end of the fiber. In this work, the results of an experimental study on the relationship between the modal noise and the length and diameter of fiber, and the coherence length of the source used are presented, illustrating the major considerations for the use of multimode fiber in a white light interferometer.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
