Abstract
A fiber Bragg grating interrogator assembly is described. Examples of the fiber Bragg grating interrogator assembly include an optical fiber including a fiber Bragg grating having a variable Bragg wavelength (λ) and a dynamic range of interest (Δλ) over which the Bragg wavelength (λ) can shift during use. The fiber Bragg grating interrogator assembly also includes a response analyzer having a spectrally selective device with an input port to which the optical fiber is operably connected, and a plurality of output ports of which each output port is associated with a respective spectral range (Δλ). The spectral ranges (Δλ, Δλ, Δλ) of each at least three successive output ports partially overlap, such that the FBG's Bragg wavelength (λ) falls inside the spectral ranges (Δλ, Δλ, Δλ) of at least three successive output ports over the dynamic range of interest (Δλ) of the FBG.
