Fiber Optic Interferometer

Adaptive fiber-optic interferometer which is based on multimode optical fiber as a sensor and diffusion holograms recorded in semiconductor photorefractive crystal CdTe:V without any electric field is developed. The interferometer sensitivity achieved is only 5.7 times less then highest sensitivity which is possible only in non-adaptive lossless classical interferometer. A practical detection limit is equal to Hz W nm 10 0 3 5 − × . , which allows to broadband detecting of an object’s displacement of order 0.2 nm or deformation of order 2 pε with using light sources having only 5 mW optical power.
