当三个或三个以上的平面波在空间中重叠时，在节线上会发生完全相消干涉，也称为相位奇点或光学涡旋。对于三个平面波的叠加，涡是直的，平行的线。对于四个平面波的旋涡形成一个阵列的封闭或开放的循环。对于五个或更多的平面波，环是不规则的。我们说明这些模式的数值和实验，并解释三，四，五波拓扑结构与相量参数。
When three or more plane waves overlap in space, complete destructive interference occurs on nodal lines, also called phase singularities or optical vortices. For super positions of three plane waves, the vortices are straight, parallel lines. For four plane waves the vortices form an array of closed or open loops. For five or more plane waves the loops are irregular. We illustrate these patterns numerically and experimentally and explain the three-, four- and five-wave topologies with a phasor argument.
