Abstract

A novel intensity-modulated fiber Bragg grating (FBG) sensor system employing fiber dispersion is presented. A signal is generated at a photodetector by two modulated signals reflected from a sensing and a reference FBG. wavelength shift of the sensing FBG changes intensity of RF signal due to a fiber dispersion-induced phase change, temperature effect being compensated automatically by the FBG. Strain measurement with a maximum sensitivity of -0.34 ìV/ìå has been achieved.
