Abstract
ABSTRACT
A hybrid sensor that operates in the intensity domain by converting the polarization and wavelength information from the photonic crystal fiber sensor and fiber Bragg grating (FBG) sensor, respectively, into intensity variation is presented in this paper. The hybrid fiber-optic sensor system involves a combination of a polarimetric sensor based on a photonic crystal fiber and a FBG sensor and is used for simultaneous strain and temperature measurement. The strain sensitivity of the polarization maintaining photonic crystal fiber at different lengths and the corresponding slope required for the edge filter which converts the FBG wavelength information into intensity are studied and presented in this paper. The proposed sensor configuration has a wide range of applications in smart fiber-optic sensing.
