High Resolution Demodulation of Fiber Bragg Grating via Computationally Efficient Levenberg Marquardt Method
This paper introduces a computationally efficient Logarithmic Gaussian Levenberg-Marquardt (LGLM) algorithm for FBG demodulation, which significantly enhances system stability and improves range deviation by more than 11.6 times compared to traditional Gaussian fitting methods.
