摘要

In this paper we propose and implement the simultaneous interrogation of high and low reflectance fiber Bragg grating (FBG) sensors in both the wavelength and the time domain by utilizing a single conventional broadband laser source. Our results have confirmed the ability of the wavelength domain section of the proposed scheme to resolve the cross strain and temperature measurements of 300 µe and ...
