Abstract:Torsion sensing is a promising technique in a variety of different scientic and industrial applications. In this paper, we present a novel torsion sensor based on the cascaded long-period ber
grating inscribed in a four-mode ber (CLPFG-FMF). The change in rotatory vector makes resonant wavelength shift, for the twisted CLPFG-FMF. The key factor, which severely impacts on the properties and performance of torsion sensor, is also investigated and discussed. Experimental results show that the resonant wavelength linearly shifts with the torsion rate and the cascaded angle plays an important ro
