Abstract
A fiber Bragg grating (FBG) interrogation method allows for high frequency dynamic measurement. The method may utilize a broad band light source connected to the sensing elements. Each sensing element may comprise two wavelength matching FBGs, a coupler, and a photodiode. The FBG closest to the light source may attenuate the central wavelength in the transmission spectrum and thus the reflection spectrum of the second FBG. Variations in intensity of the second FBG may be measured by the photodiode and can be calibrated to the desired measurands.
