چکیده
We describe a frequency-modulation technique that is applicable to two-beam interferometric systems illuminated by semiconductor diode lasers. The technique permits a determination of the optical path difference between the two arms of the interferometer and is used here to extend the range of a fiber polarimetric strain sensor by determining the order of the particular polarimetric fringe under consideration.

Polarimetric DBR fiber laser sensor for strain-temperature discrimination
A polarimetric Distributed Bragg Reflector (DBR) laser sensor in a low birefringent Er-doped fiber has been proposed. The spectral overlap of two uniform fiber Bragg gratings (FBG) has been employed as filtering technique to achieve a Single Longitudinal Mode (SLM) regime. By measuring the RF beat frequency between the two orthogonal polarized lasing modes and the absolute wavelength of one mod...

متن کاملInteraction between Optical Fibre Sensors and Matrix Cracks in Crossply Gfrp Laminates. Part 2: Crack Detection 4. Crack Detection Using the Polarimetric Sensor and an Fft Band Pass Filter
Polarimetric optical fibre sensors have been embedded within the 0° ply and close to the 0/90 interface of transparent cross-ply GFRP coupons. The coupons have been subjected to an increasing quasi-static load so that transverse ply cracks initiate and propagate across the coupon. Crack accumulation has been monitored using the optical output signal from the polarimetric sensor, strain measurem...
متن کاملIntrinsic Fabry-Perot Interferometric Fiber Sensor Based on Ultra-Short Bragg Gratings for Quasi-Distributed Strain and Temperature Measurements
(Abstract) The health monitoring of smart structures in civil engineering is becoming more and more important as in-situ structural monitoring would greatly reduce structure life-cycle costs and improve reliability. The distributed strain and temperature sensing is highly desired in large structures where strain and temperature at over thousand points need to be measured simultaneously. It is d...
متن کاملPolarization- and frequency-stable fiber laser for magnetic-field sensing.
We report a novel polarimetric fiber laser sensor for magnetic-field-current measurement that is stable to variation of temperature and strain because it employs a Faraday rotating mirror. We obtained a sensitivity of 10.24 kHzyA with good linearity and greatly improved the signal-to-noise ratio by reducing the number of laser cavity modes with the help of a saturable absorber.
