This paper presents a polarimeter for simultaneous measurement of variation in magnitude phase retardation, azimuth and principal axis angle of the incident light. The configuration is based on dual-liquid-crystal-modulator (Dual-LCM) which is used to enhance the measurement's S/N and resolution. The changes of these three parameters are measured by a very simple digital signal processing system. Compared to the conventional configurations, the proposed polarimeter offers an easier setup, high system stability and repeatability. The results show that our system has the advantages of wide measurable domain for the whole-polarization and high measurement precision. The results indicate that the maximum absolute errors of the phase retardation, azimuth and principal axis angle are 0.24°, 0.14° and 0.31°, respectively. Finally, the dynamic ranges of the principal-axis angle measurement and the phase-retardation measurement extend as far as 360° and the measurement precision is below 0.31°.
