Abstract

A new thermally-compensated bending gauge using surface-mounted fiber Bragg gratings is demonstrated. The gauge configuration involves two fiber Bragg gratings, surface-mounted on opposite surfaces of a bent mechanical structure. Experimental results using a cantilever beam are presented, showing a strain resolution of 9 microstrain.
