## Abstract A cantilever beam and fiber Bragg grating are used to measure acceleration. The output signal is insensitive to temperature variations from โ20ยฐC to 40ยฐC, and the output signal fluctuates less than 5% without any temperature compensation schemes. For the experimental system, a linear ou
A novel di erential double Bragg grating sensor for temperature-insensitive strain measurement is presented. The sensor consists of two identical weak measuring and reference gratings separated by some distance. The reference grating is placed inside the silica capillary that made it almost strain i
