Abstract
A fiber Bragg grating interrogator assembly, comprising: an optical fiber including a fiber Bragg grating (FBG;) having a variable Bragg wavelength (λ) and a dynamic range of interest (Δλ) over which the Bragg wavelength (λ) can shift during use; —a light source operably connected to the optical fiber, and configured to illuminate the fiber Bragg grating to solicit a response therefrom; and an response analyzer, including: a spectrally selective device having an input port and a plurality of output ports (-), wherein the input port is operably connected to the optical fiber and wherein each of the output ports is associated with a respective spectral range (Δλ), said spectrally selective device being configured to provide a spectral energy distribution of a response of the fiber Bragg grating received on the input port onto said output ports.
