## Abstract A novel fiber Bragg grating (FBG) tilt sensor is proposed to detect the magnitude and the direction of a twoβdimensional inclination by using four FBGs. High angle sensitivity and measurement resolution have been achieved, and the temperature effect has been eliminated completely withou
## Abstract A novel temperatureβindependent strain sensor based on a fiber Bragg grating is demonstrated. The front section of the fiber Bragg grating is fixed to a crystal plate, and the other section is linearly etched in HF acid. The reflected power of the grating varies linearly with strain and
