Abstract
In this paper we present a fiber Bragg grating shift demodulator with changeable resolution based on an unbalanced fiber Mach–Zehnder interferometer. Preliminary research proves phase sensitivity to Bragg wavelength changes of 6,83 rad/mε. Phase sensitivity can be modified by changing the optical path difference witch is only limited by the coherence length of light reflected by the fiber Bragg grating. This solution can be used as a single sensor or as a part of a more complex system.
