Among fiber optic sensors, FBGs emerge as the most successful due to the fact that sensing information is encoded in an absolute parameter, namely the resonant wavelength. Nevertheless, the need to convert this absolute parameter into an optical intensity modulation, more suited to be handled using low cost instrumentation, also imposes additional constrains to their practical implementation. In this paper a double conversion interrogation technique is proposed, which provides a robust low-cost system for FBG sensor demodulation. This FBG interrogation technique uses all-fiber low-cost devices. A long period grating has been employed as spectral filter for wavelength-to-amplitude conversion, providing a high measuring range (>2 nm). By dividing the signal before filtering, adding a delay line and recombining after filtering, power referencing is achieved in the optical domain thus employing only one detector. Insensitivity to power variations as high as 75% of the total optical power has been proven.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest.

Both Fabry-Perot and distributed feedback fiber (DFB) laser sensors have been investigated for the measurement of strain, uniaxial pressure and magnetic fields (H.K. Kim et al, 1993; G.A. Ball et al, 1993; H.K. Kim et al, 1995; J.T. Kringlebton et al, 1996; S.-Y. Huang et al, 1990). In this paper, a Fabry-Perot type fiber laser sensor for fluid pressure is reported. The pressure acts directly on an elliptical core sensing fiber (S.-Y. Huang et al, 1990; W.J. Bock and W. Urbanczyk, 1996) doped with erbium. As a result, no mechanical transducer is required, which makes possible a sensor with very small diameter. Fiber Bragg gratings (FBG) are used as reflectors for the laser. Configurations with the gratings written into circular core fibers, as well as into the doped elliptical core fibers, are analyzed. It is shown that the dispersion of the highly birefringent gratings can be employed to significantly improve the sensor resolution into the range of a few 10/sup -6/ of the full scale signal. Possible applications of the sensor include pressure monitoring in oil wells and other hostile environments.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest.
