## 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 vibration sensor based on a fiber Bragg grating (FBG) is demonstrated.The FBG was glued in a slanted direction onto the lateral side of a rightβangled triangle cantilever beam. Vertical vibration applied to the cantilever beam leads to a periodical variat
In this paper, we present a Fiber-Bragg-Grating-based temperature sensor. The technique employs heterodyne detection using two Fiber Bragg Gratings. One of the gratings is used as a reference (local oscillator) and the second as a sensing arm. This sensor uses a Folded Mach-Zehnder interferometer. A
## Abstract A fiber Bragg grating (FBG) pressure sensor packaged by using a hard core in the membrane is presented. By utilizing the unique membraneβbased FBG packaging method, its pressure sensitivity has been effectively enhanced. The pressure sensitivity of the FBG reaches 5.75 Γ 10^β3^/MPa with
