Abstract

The use of gas absorption lines as multiwavelength references to enhance the measurement accuracy of fiber bragg grating (FBG) sensors were reported. The experiments with an external cavity tunable laser and acetylene absorption lines for a three-FBG sensor system demonstrated a wavelength measurement accuracy of -2pm. The Bragg wavelengths of the FBGs were determined by using linear relation and the FBG wavelengths obtained from the gaussian fitting. The standard deviation of the Bragg wavelengths for three FBGs was found to be 2.1pm, 1.9pm, and 2pm.
