Abstract
Since many years one of the topic our research team are multi-parametric fiber optic polarization sensors. In the paper is presented a new version of the Fiber-Optic Interferometric Polarization Analyzer (FOIPA). This system is based on modified Sagnac interferometer and it was equipped with automatic current driven polarization controllers driven by special analog output card and detection system based on data acquisition card and LabVIEW software. This system was called full automatic fiber optic interferometric polarization analyzer. Used in the system automatic, temperature driven polarization controllers allow working in feedback electronic loop with data acquisition system and they function as calibration and stabilization subsystem. Specially developed detection system allow measuring amplitudes of first three tones of the AC parts of two electric signals as well as they DC voltages. That advantages have given possibility replaced an expensive lock-in amplifier and make data performance and polarization parameters calculation more faster and easier. It was necessary to implement special procedure to proper SOP identification In the paper are presented theoretical and experimental analyzes of the uncertainties, also. Finally a comparison with commercially available polarization analyzer is shown.
