A volume holographic spectral filter bank formed in photorefractive BaTiO3 is proposed and demonstrated as a demodulation scheme for in-fiber Bragg grating sensors. A strain range of 2500 microsecond(s) train, with minimum detectable strain of 4 microsecond(s) train/(root)Hz is reported. Extension of the technique to allow intensity referencing and parallel demodulation of an array of sensors is discussed.
