Abstract

A simple multipass interferometer is described that takes advantage of the limited coherence length of a light source in order to increase the sensitivity. The sensitivity augmentation is accomplished by insertion of a beam splitter into one leg of the interferometer, thereby achieving multiple reflections between the end mirror and the beam splitter. The path length of the other leg is then varied corresponding to one, two, three, or more reflections, resulting in a onefold, twofold, threefold, etc. increase in sensitivity.
