Fiber Bragg grating (FBG) sensors has stood out as a flexible and particularly suitable tool for power transformer monitoring being a passive and dielectric sensor element.
According to the wave vector direction, the spatial period distribution and the period length, fibre gratings are classified into four basic types: fibre Bragg grating, blazed fibre grating, chirped fibre grating and
This article explains what fiber Bragg gratings (FBGs) are: periodic modulations of the refractive index in a fiber core which reflect a narrow wavelength band
Fiber Bragg Grating (FBG) is defined as a passive filter device that consists of a diffraction grating created by periodic modulation of the refractive index in the fiber core, allowing it to reflect specific
