Claim 27:
28. A method, comprising:
selecting at least one of a light source and a fiber Bragg Grating (FBG) sensor for a FBG interrogation system such that a first portion of a transmitted spectrum of the light source is configured to interact with a second portion of a reflected spectrum of the FBG sensor over a discriminating spectral domain;
transmitting, via the light source, an optical signal;
receiving, from the FBG sensor, a reflected optical signal representative of a change in a physical signal sensed by the FBG sensor; and
transforming, at a photodetector, the reflected optical signal into an electrical signal, wherein a measurement of the electrical signal is indicative of the change in the physical signal.
