Feasibility of Fiber Bragg Grating and Long-Period Fiber Grating Sensors under Different Environmental Conditions
This paper presents the feasibility of utilizing fiber Bragg grating (FBG) and long-period fiber grating (LPFG) sensors for nondestructive evaluation (NDE) of infrastructures using Portland cement concretes and asphalt mixtures for temperature, strain, and liquid-level monitoring. The use of hybrid FBG and LPFG sensors is aimed at utilizing the advantages of two kinds of fiber grating to implem...
متن کاملStrain Measurement of Composite Laminates Using Fiber Bragg Grating Sensors
Fiber Bragg grating(FBG) sensors, one of the fiber optic sensors(FOS), based on the wavelength division multiplexing(WDM) technology are ideally suitable for structural health monitoring of composite materials and structures. Proper monitoring of measurands in FBG sensor systems requires accurate measurement of the Bragg center wavelength, and the ability to track rapid shifts of the wavelength...
متن کاملResearch of a novel fiber Bragg grating underwater acoustic sensor
A new type of optical fiber underwater acoustic sensor (hydrophone) constructed with two fiber Bragg gratings (FBG) and a self-demodulation ethod is presented in this paper. Unlike other FBG sensors which have separate sensing and demodulating elements, this FBG hydrophone has nly a single structure for both sensing and demodulating using a pair of matched FBGs. The cylindrical structure of the...
متن کاملFiber Bragg Grating-Based Vibration Sensing for Machine Prognostics
We report results from a fiber Bragg grating (FBG) based scheme for vibration sensing in combustion engines. The vibration sensing is carried out using a commercial high speed spectrometer. We compare the performance of the FBG sensor with commercial PZT-based sensors and find that the FBGs perform as well.
متن کاملDevelopment of Fiber Bragg Grating Sensor System Using Wavelength-swept Fiber Laser
Fiber Bragg grating (FBG) sensors based on the wavelength division multiplexing technology are ideally suited for structural health monitoring. In many applications, it is desirable to form several arrays of optical fiber sensors to monitor the response of structures. In the present study, we constructed an improved FBG sensor system using a wavelength-swept fiber laser which exhibits high outp...
