In this paper, we mainly introduce a novel measurement system of the polarization extinction ratio(PBSBC system). Here, because the main optical components of the system is PBS and PBC, so we call this system PBSBC system. First of all, we introduce the principle of method of measuring the polarization extinction ratio by drawing a circle on the Poincare. Secondly, we present the system block diagram of PBSBC system, and design an experimental system to theoretically and experimentally investigate the performance of this system though the multiple groups of experimental data collected under the same condition. Finally, we could show that it is compatible with the analysis in PBSBC system.
