摘要: The temperature dependence of the force sensitivity a regenerated fiber Bragg grating (RFBG) in smf28 was experimentally determined up to temperatures 400°C for first time. found decline linearly with increasing temperature. RFBG showed pure elastic response applied forces and no wavelength drift occurred during measurement. This demonstrates that based sensors are suited monitoring at 400°C.
