针对非均匀复杂偏振光束难以用一种偏振状态描述的现象，提出了一种点对点的偏振光检测方法，该方法能够同时检测光束横向切面内所有点的偏振态，为非均匀偏振光描述提供足够的信息，解决了柱状矢量偏振光光束的质量检测问题。运用这种方法，对已知偏振光束进行验证检验取得了良好的效果，证明了该方法可以作为一种可靠、稳定的方法用对柱状矢量偏振光检测与评价。另外，一些描述柱状矢量偏振光均匀性的参数被重新定义，为柱状偏振光的质量描述提供了量化指标。

The polarization state of inhomogeneous complex polarized beam is hard to describe and detect. A point-to-point polarized light measuring method is proposed which can get the polarization of all the points in the cross section in one detection and provide enough information describing inhomogeneous polarized beam, especially describing radically and azimuthally polarized beams. Detecting known polarized beams with this method, good results are obtained, which demonstrate the point-to-point method stable and reliable to detect the cylindrical vector beams. Parameters used to depict the uniformity of cylindrical polarization beams are also redefined, which provide the quantitative indexes supporting the measurement of cylindrical polarization beams.
