| Abstract(in English) | Recently, we proposed multiplexed long-length FBG sensors based on synthesis of optical coherence function (SOCF) to realize distributed sensing at multipoint regions inside monitoring structure. Although SOCF is supposed to be used at a region within coherence length of laser source, it was found to be available at a region beyond coherence length for distributed measurement. In this paper, measurement of Bragg-wavelength distribution inside a long-length FBG at region beyond laser coherence length is demonstrated for elongation of measurement range. |
