Abstract

Simultaneous measurement of the bending curvature and axial stress by using dual fiber Bragg gratings and a sidepolished technique is presented. Curvature measurement, using side-polished fiber Bragg gratings with different thicknesses ranging from 93.94 to 70.66 μm shows corresponding sensitivities from 0.096 to 0.402 nm/m^-1 for bending curvatures in the range of 0 - 3 m^-1. The simultaneous axial stress is measured based on the shift in the Bragg wavelength and ranges from 0.008 - 0.128 GPa. A maximum sensitivity of 13.83 nm/GPa is demonstrated.
