Cylindrical vector polarized (CVP) beams are widely used in many applications due to their special polarized distribution and highly focused properties. It is crucial to evaluate the polarization performance of CVP beams. This paper proposes several polarization parameters for comprehensively evaluating the overall polarization performance and spatial polarization symmetry of CVP beams. To verify this method, several different CVP beams are simulated, and the polarization performance of these beams are indicated. In addition, the trapping models are built to compare trapping capacities of the beams with different polarization performance. The results indicate that the ideal CVP beams demonstrated a higher trapping force than the non-ideal ones, and the trapping force was sensitive to the spatial polarization symmetry of the beams. This evaluation method plays an important role in applications that are susceptible to the polarization performance of the beams.

圆柱矢量偏振 (CVP) 光束由于其特殊的偏振分布和高度聚焦的特性而被广泛应用于许多应用中。评估 CVP 光束的偏振性能至关重要。本文提出了几种偏振参数，用于综合评估CVP光束的整体偏振性能和空间偏振对称性。为了验证这种方法，模拟了几种不同的 CVP 光束，并指出了这些光束的偏振性能。此外，建立捕获模型以比较具有不同偏振性能的光束的捕获能力。结果表明，理想的 CVP 光束表现出比非理想光束更高的俘获力，并且俘获力对光束的空间偏振对称性很敏感。
