A Novel Demodulation Method For Fiber Bragg Grating

Fiber Bragg Grating Finite Element Method

This method combines the finite element method (FEM) and eigenmode expansion method (EEM). The function of the FEM is to calculate all guided modes that match the boundary conditions of optical fiber waveguides. Compared with coupled-mode theory (CMT), which is widely used for studies involving optical fiber Bragg gratings (FBGs), the proposed investigation scheme is visualized, diagrammatic, and simple. Originally adapted from (https://github. This study focuses on demonstrating the relevance between design period and spectral characteristics of SFBGs. In this study, a numerical simulation method was employed to investigate and analyze superstructure fiber Bragg gratings (SFBGs) with five duty cycles (50%, 33.

Fiber Optic Sensor Demodulation Circuit

This paper presents a method that integrates neural networks with arrayed waveguide gratings (AWGs) for the demodulation of fiber-optic sensors based on the Vernier effect and a novel, to our knowledge, Fabry–Pérot (FP) strain sensor structure. Some embodiments of the disclosure provide a demodulation system for obtaining phase change parameters by a fiber-optic Fabry Perot sensor. In an embodiment, the demodulation system includes a transmitting module, a fiber-optic Fabry Perot sensor, a light splitting module, a filter module, a. Fiber optic Fabry-Perot sensors have attracted a lot of attention in many fields such as medical detection, underwater acoustic detection, and electric power monitoring due to their high sensitivity and strong anti-interference ability. The demodulation process is typically developed using analog circuits.
