Hybrid fibre optic sensor system for measuring the strain, temperature and thermal strain of composite materials

Journal Article


Abstract


  • This paper proposes a hybrid optical fiber sensor

    system for simultaneously sensing the strain, temperature,

    and thermal strain of composite materials. The hybrid fiber

    optic sensor system involves a combination of three sensors:

    1) a polarimetric sensor based on an acrylate coated polarization

    maintaining photonic crystal fiber (PM-PCF); 2) a coating

    stripped PM-PCF sensor; and 3) a fiber Bragg grating sensor

    (FBG). Temperature is sensed using the FBG sensor, axial strain

    is sensed using the acrylate coated PM-PCF sensor, and thermal

    strain is sensed using the coating stripped PM-PCF. The hybrid

    sensor system presented operates in the intensity domain by

    converting the polarization and wavelength information from the

    polarimetric sensors and the FBG, respectively, into detectable

    linear intensity variations. Subsequently, by deriving a characteristic

    matrix for the hybrid sensors, information about temperature,

    axial strain, and thermal strain can be simultaneously

    determined. An experimental demonstration of the hybrid sensor

    system is described based on a glass fiber reinforced composite

    material sample within which the three different sensors are

    embedded. The proposed sensor configuration can be employed

    in composite material structural health monitoring applications
