TLDR
In this paper, a free active cylinder bulk-modulus and the birefringence effect on a fiber Bragg grating (FBG) is implemented by demodulating fiber BRG peak splitting caused by transverse stress differences in the core of a single mode fiber, which is bonded on the exterior surface of the cylinder.About:

FBG-type sensor for simultaneous measurement of force (or displacement) and temperature based on bilateral cantilever beam
TL;DR: An improved FBG-type sensor for simultaneous measurement of force and temperature based on the bilateral cantilever beam (BCB) is proposed and demonstrated in this paper, where two parts of the beam are subject to opposite forces (or displacements) leading to a red shift for the part of the FBG subject to stretch and to a blue shift for other one.
