Fiber Optic Bragg-Grating Sensors
In-fibre Bragg gratings are sensor elements which are photo-written into optical fibre using intense ultra-violet laser beams and have the potential for the measurement of strain/deformation and temperature with applications reported including monitoring of highways, bridges, aerospace components and in chemical and biological sensors. The development of a fiber Bragg grating (FBG) measuring sy...
متن کاملMicrowave Photonics for High-Resolution and High-Speed Interrogation of Fiber Bragg Grating Sensors
Conventional fiber Bragg grating sensors have a few limitations, such as limited interrogation resolution and speed and difficulty in separating different measurands. In this article, microwave photonic techniques applied to fiber Bragg grating sensors to improve the interrogation resolution and speed are discussed. Experimental results to validate the techniques are provided.
متن کاملUse of a single-multiple-single-mode fiber filter for interrogating fiber Bragg grating strain sensors with dynamic temperature compensation.
An interrogation technique for fiber Bragg grating (FBG) strain sensors with dynamic temperature compensation using a single-multiple-single-mode (SMS) fiber filter as a temperature compensating element is presented. Experimental results show that this technique offers a resolution of better than 3.4 muepsilon for strain measurements in the range from 0 to 1667 muepsilon, and the temperature in...
متن کاملMulti-Stress Monitoring System with Fiber-Optic Mandrels and Fiber Bragg Grating Sensors in a Sagnac Loop
Fiber Bragg grating sensors are placed in a fiber-optic Sagnac loop to combine the grating temperature sensors and the fiber-optic mandrel acoustic emission sensors in single optical circuit. A wavelength-scanning fiber-optic laser is used as a common light source for both sensors. A fiber-optic attenuator is placed at a specific position in the Sagnac loop in order to separate buried Bragg wav...
