Multiplexed fiber Bragg grating strain-sensor system with a fiber Fabry - Perot wavelength filter.
There has been considerable interest recently in the development of fiber-optic sensors based on in-fiber Bragg gratings (FBG's), which can be written into Ge-doped fibers by use of a transverse holographic method.' The use of such elements for distributed strain or temperature sensing in advanced composite or other structural elements and their use as inline reflectors in interferometric syste...
متن کاملStrain Transfer Analysis of a Clamped Fiber Bragg Grating Sensor
Clamped fiber Bragg grating (FBG) sensors have been widely applied in engineering strain measurements due to their advantages of high flexibility and efficiency. However, due to the existence of the interlayer, the strain measured by the encapsulated FBG sensor is not equal to the strain of the host material, which causes strain measurement errors. In this paper, the strain transfer analysis of...

متن کاملInterrogation of interferometric sensors with a tilted fiber Bragg grating.
This paper describes the interrogation of interferometer-based transducers with a technique that involves the use of a tilted fiber Bragg grating. The interrogation process will be analyzed both from the conceptual and experimental points of view. Simultaneous interrogation of multiplexed interferometric transducers is successfully checked using this technique.
متن کاملA Magnetostrictive Composite-Fiber Bragg Grating Sensor
This paper presents a light and compact optical fiber Bragg Grating sensor for DC and AC magnetic field measurements. The fiber is coated by a thick layer of a magnetostrictive composite consisting of particles of Terfenol-D dispersed in a polymeric matrix. Among the different compositions for the coating that were tested, the best magnetostrictive response was obtained using an epoxy resin as ...
