A sensitive fiber-speckle field sensor using a Ce:Fe-doped LiNbO3 photorefractive fiber hologram is introduced. We have shown that the sensitivity of this photorefractive fiber specklegram sensor can be of the order of 0.05 μm. The proposed system would offer the widespread use of practical fiber-sensing applications.
