Detector for an optical-fiber acoustic sensor using dynamic holographic interferometry

Not Accessible

Your library or personal account may give you access

Abstract

It is shown that the acoustically induced phase modulation of coherent light propagating within a multimode optical fiber may be linearly detected by an interferometer employing an unmodulated replica of the fiber beam as the reference. It is proposed that a dynamic hologram provide such a reference. This technique allows a performance comparable with that of a monomode interferometric sensor to be obtained, but with considerably relaxed alignment tolerances.
