Bragg diffraction grating
WebNov 4, 2024 · Fibre Bragg Gratings The following section describes the measurement method that was used. An FBG is a periodic change in the refraction index within the core of a glass fibre. Thus, a strain sensitive area is given along the fibre’s axis, which is measured by an optical interrogator. WebSchematic diagram of the RPBS. Unpolarized light is incident at the Bragg angle. The grating presents only two dif- fraction orders by reflection: the zeroth order and the …
