Compact high-resolution FBG strain interrogator based on laser-written 3D scattering structure in flat optical fiber

Abstract We demonstrate a fiber Bragg grating (FBG) strain interrogator based on a scattering medium to generate stable and deterministic speckle patterns, calibrated with applied strain, which are highly dependent on the FBG back-reflection spectral components. The strong wavelength-dependency of s...
