Fiber Bragg Grating Sensor Array Design
The modeling, design, simulation, fabrication, calibration, and testing of a three-element, 15. 3 cm fiber Bragg grating strain sensor array with the coherent optical frequency domain reflectometry (C-OFDR) interrogation technique are demonstrated. This review provides a comprehensive overview of FBG sensor technology. Abstract—Exceptional points (EPs), intrinsic to non-Hermitian systems, exhibit singular spectral responses with extreme sen-sitivity to external perturbations, offering new opportunities for precision sensing. In this work, we investigate the sensing performance of Fiber Bragg Gratings (FBGs). Fiber Bragg Grating (FBG) technology is one of the most popular choices for optical fiber sensors for strain or temperature measurements due to their simple manufacture, as we will see later on, and due to the relatively strong reflected signal. FBG sensors offer advantages such as small size.

Long-period fiber Bragg grating sensing principle
The fundamental principle behind the operation of an FBG is, where light traveling between media of different refractive indices may both and at the interface. The refractive index will typically alternate over a defined length. The reflected wavelength (), called the Bragg wavelength, is defined by the relationship, where is the effective refractive index of the fiber core and is the grating period. The effective refractive.
