چکیده
A polarimetric fiber-optic vibration sensor immune to temperature variations is reali2ed by forming coils using a standard single-mode fiber. The phase drift due to the linear birefringence changes induced by a modification of the environmental temperature is balanced by a feedback compression of a non vibrating coil. Experimental results show that without the

متن کاملDetector for an optical-fiber acoustic sensor using dynamic holographic interferometry.
It is shown that the acoustically induced phase modulation of coherent light propagating within a multimode optical fiber may be linearly detected by an interferometer employing an unmodulated replica of the fiber beam as the reference. It is proposed that a dynamic hologram provide such a reference. This technique allows a performance comparable with that of a monomode interferometric sensor t...
متن کاملRecent Progress in Distributed Fiber Optic Sensors
Rayleigh, Brillouin and Raman scatterings in fibers result from the interaction of photons with local material characteristic features like density, temperature and strain. For example an acoustic/mechanical wave generates a dynamic density variation; such a variation may be affected by local temperature, strain, vibration and birefringence. By detecting changes in the amplitude, frequency and ...

Distributed sensing systems can transform an optical fiber cable into an array of sensors, allowing users to detect and monitor multiple physical parameters such as temperature, vibration and strain with fine spatial and temporal resolution over a long distance. Fiber-optic distributed acoustic sensing (DAS) and distributed temperature sensing (DTS) systems have been developed for various appli...
متن کاملStabilized Interrogation and Multiplexing Techniques for Fiber Bragg Grating Vibration Sensors
We demonstrated a simple interrogation system for multiplexed fiber Bragg grating sensors with high frequency range. A tunable Fabry-Perot filter with narrow free spectral range (FSR) was used to simplify the multiplexing demodulator for FBG vibration sensors. A stabilization controlling unit was also developed for the maintenance of maximum sensitivity of the sensors. In order to verify the pe...
