Abstract
We demonstrate a high-sensitivity, relatively simple and inexpensive technique for interrogation of fiber-Bragg- grating sensors, where the signals from the sensor are resolved with a fiber-Bragg-grating filter tuned by a cantilever beam. We achieve a wavelength resolution of 0.002nm, which corresponds to a strain resolution of 1.7(mu) (epsilon) or a temperature resolution of 0.03 degrees C.
