从基本定义出发，导出了多色矢量光场中利萨焦奇点的手性的显式表达式，并将其用于研究利萨焦奇点在自由空间中的手性及其通过像散透镜的传播。研究发现，手性不仅与构成多色矢量电场分量的Stokes参数ss3i （i= 1,2, ......,n）有关，还与它们的频率和振幅因子有关。
Starting from the basic definition, the explicit expression for the handedness of Lissajous singularities in polychromatic vector optical fields is derived, which is illustrated and used to study the handedness of Lissajous singularities in free space and propagation through an astigmatic lens. It is found that the handedness is not only related to the Stokes parametersS3i(i= 1, 2, ……,n) of constituting components of the polychromatic vector electric field,but also to their frequencies and the amplitude factors.
