Paper Abstract

A sensing scheme for multimode fiber-optic interferometer using a photorefractive double phase conjugator is proposed. The conjugator acts as a converter of light amplitude distribution of the fiber modes into the same wavefronts propagating in the same direction. The scheme has high light efficiency and allows interferometric detection of high speed intermodal phase fluctuations and it is self adaptive for environmental changes. The results of experiments for vibration detection are presented to demonstrate the feasibility of the proposed scheme. In our experiments, a double phase conjugator based on photorefractive waveguide- like BTO crystal was used.
