Claim 0:
1. A miniaturized fiber Bragg grating (FBG) interrogation system comprising:
at least one light source having a transmitted spectrum;
at least one FBG sensor including a plurality of Bragg gratings, wherein the at least one FBG sensor has a reflected spectrum and is configured to receive an optical signal from the at least one light source, the at least one FBG sensor further configured to generate a reflected optical signal representative of a change in a physical signal sensed by the at least one FBG sensor; and
a photodetector optically coupled to the at least one FBG sensor and configured to transform the reflected optical signal into an electrical signal,
wherein the at least one light source and the at least one FBG sensor are configured such that the transmitted spectrum and the reflected spectrum interact over a discriminating spectral domain.
