摘要：

Highly precise fiber optic strain and temperature measurements using chirped long period fiber grating (CLPG) are proposed and demonstrated, in which cascaded CLPGs (C-CLPGs) are employed as the sensing element and a Fourier transform technique is applied for the interrogation scheme. In this technique, strain and/or temperature-induced wavelength shift is determined precisely from the cross-correlation or cross-spectrum between the original and shifted channeled spectrum. In the experiment, C-CLPGs are fabricated by UV-irradiation technique, and strain and temperature characteristics are investigated. The highly precise measurements are confirmed by comparing with the results of the peak tracking method.
