Abstract

This work presents a novel two-wavelength interferometer based on fiber Bragg gratings. Two light sources with different wavelengths are generated from separate fiber Bragg gratings. The high wavelength accuracy of fiber Bragg gratings allows us to enhance the measured accuracy of the interferometer. In addition, a Michelson interferometer is used to reliably measure the path-length difference signal, thereby demonstrating the proposed interferometer's effectiveness.
