摘要
复合涡旋可以通过不同的光学涡旋叠加产生,通过两束平面涡旋共线叠加,对两束平面光学涡旋的叠加作了理论分析.讨论了不同情况下复合涡旋中心的分布情况,通过几何解析法找到了涡旋核重合的两平面涡旋叠加后的复合涡旋中心,从理论上得出,这种叠加方式可以得到圆对称分布的复合涡旋.
The superposition of different optical vortices can produce composite vortex.It makes a theoretical analysis about the superposition of two planar optical vortex beams is made through the collinear superposition of two planar vortex beams,the distribution of composite vortex center in different situations is discussed,and through the geometric analytic method the composite vortex center which is produced by two plane vortices superposed whose vortex cores are coincident is found.In the theory,the composite vortex of the circularly symmetric distribution can bg gotten through this superposition method.
