    ABSTRACT: In this paper, we discuss a particular topology of a fiber-optic pressure transducer, developed recently at the Laboratory of the Photonics Research Center, University of Quebec en Outaouais. The sensor, which is an extension of our previous polarimetric configuration, was designed to operate using typical telecommunications components at the wavelength of 1300 nm. The pressure sensor is temperature compensated in an innovative way and has no polarizer between the LD and the sensor. The absolute accuracy of this sensor can be less than 1% in a wide range of temperatures, and including all types of metrological errors such as hysteresis and unrepeatability.

    ABSTRACT: A self-calibrating automated characterization system for depressed cladding applications is demonstrated utilizing the laboratory virtual instrument engineering workbench (LabVIEW) software and general purpose interface bus (GPIB) interface. The automation system consists of a tunable laser source (TLS), optical spectrum analyzer (OSA), attenuator, laser diode controller, and a personal computer, and all these instruments are networked using GPIB cables. Compared to manual measurement techniques, the overall experiment time is reduced by 80% while the data acquisition increases in accuracy, with a lower uncertainty value of plusmn 0.012 dB after self-calibration. From the experiment, the use of the automated self-calibrating software has allowed for the characterization of the depressed cladding erbium-doped fiber (EDF).

    ABSTRACT: Polarimetric fiber optic sensing is based on measurements of polarization changes of light transmitted inside single mode fiber affected by external phenomena. Polarimetric optic sensors are mainly used for static measurements of strain, stress and high pressure. In the paper the results of dynamic strain measurements of a steel rail by use of the polarimetric fiber optic sensors are presented. We can observe a quick response of optical fiber measuring system for changes of strain in the rail for different frequencies as well as wide range of dynamic amplitude changes
