Abstract

The authors present a method to measure the fringe visibility of the optical fiber interferometer in a dynamic and real-time way. The measurement is realized by the light modulation method. An interferometer is taken as an example to explain the measuring principle, and some typical experimental results are given. The interferometer used is constructed by the graded index multimode fibers with 50 micrometers core diameter.
