Abstract：Angular error of polarizer in polarimetric measurement is an important element affecting the measurement accuracy of degree of polarization, so angular error of polarizer should be considered in remote sensing of high-accuracy quantitative polarization. Simulation study shows that polarimetric measurement is relative to the polarization state (polarization angle or degree of polarization) of incident light in a specific measurement system of polarization. In the measurement mode of polarizer setting(0°，60°，120°), there is a maximum error of polarization measurement at the 0°or 180° polarization angle while a minimum error at the 30°，90°and 150° polarization angle; In the measurement mode of polarizer setting(0°，45°，90°), there is a maximum error of polarization measurement near the 45° polarization angle while a minimum error at the 0°，90°and 135° polarization angle. The larger degree of polarization of incident light often contributes to the bigger measurement error except for incident light with several polarization angles. So the polarization measurement may be evaluated by the average degree of polarizatioo of linearly polarized light introduced in this paper. It is indicated that the measurement mode of polarizer setting(0°，60°，120°) is better than that of(0°，45°，90°).
