Dubai Fiber Bragg Grating Strain Measurement Process
This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which enables strain gages and FBGS to be measured simultaneously, providing all data processing functions originally developed. This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which enables strain gages and FBGS to be measured simultaneously, providing all data processing functions originally developed. The work is devoted to the consideration of methods for determining the strain of objects using fiber Bragg gratings under a high-frequency vibration or pulsed mechanical action, which is difficult to perform using widespread methods and devices. The methods are based on numerical processing of the. Basically, Fiber Optic Bragg Sensors are strain-measuring devices and therefore provide many of the advantages of the well known metal foil strain gages.

Fiber Bragg Grating Temperature Simulation
This paper deals with mathematical modeling, design and application of Fiber Bragg Grating as temperature sensor. The temperature-dependent change of the refractive indices of the fiber, consequently the shift of its Bragg wavelength, is used as a measure of the temperature. The temperature sensitivity of FBGs originates from two intrinsic effects: the thermo-optic.

Fiber Bragg grating time-division multiplexing demodulation
Combined time- and wavelength-division-multiplexing demodulation technique of fiber Bragg grating (FBG) sensor arrays using a tunable pulsed laser is proposed and demonstrated. A tunable fiber laser based on a matched FBG is applied. A semiconductor optical amplifier is connected in the cavity to function as an amplifier as well as a switch.
