Author Affiliations +
A technique for the detection of dynamic strain inducedwavelength shifts in fiber Bragg grating sensors which is capable of highresolution sensing is described. The scheme is based on the use of anunbalanced-interferometer wavelength discriminator to transpose thewavelength shift of light reflected from a strained fiber grating into thephase shift of an electrical carrier signal.
