Abstract

In the paper details of analysis measurement uncertainties of the polarization parameters in the in-line fiber optic devices were presented. For measurement of polarization parameters two fiber optic devices were used. The first one Fiber-Optic Polarization Analyzer (FOPA) and the second one Fiber-Optic Interferometric Polarization Analyzer (FOIPA). The main idea of both devices operation is comparable and consists in measurement of appropriate electric signals by using polarization sensitive detectors and basing on its calculate polarization parameters. Uncertainties of measurement these parameters were considered from standard low of propagation uncertainties point of view. The experimental results obtained from testing of laboratory analyzers allow estimating standard deviations (uncertainties) and covariances measured electric quantities. Based on these information the theoretical model of uncertainties of the polarization parameters on its ranges were proposed. Results of these analyses showed that inteferometric device allows more accurate and in shorter measurement time. The polarimetric devices gives worst accuracy what was caused mainly by temperature instabilities. However measurement uncertainties of polarization parameters of both systems are better than in bulk-optic analyzers.
