一种基于跟踪干涉条纹峰值的方法被用来检测光的Pancharatnam相位，该干涉条纹峰值是随时间变化的分析仪设置的函数。这种方法的优点是证明了观察的非线性的Pancharatnam相位的某些路径上的庞加莱球条纹可见度降低到几乎为零。我们还描述了这个实验的变化与结构光束，其中Pancharatnam相位导致花图案或螺旋形干涉条纹的线性或非线性旋转。
A method based on the tracking of the peaks of interference fringes as a function of time-dependent analyzer setting is used to detect the Pancharatnam phase of light. The advantage of this method is demonstrated by observations of the nonlinearity of the Pancharatnam phase for certain paths on Poincare sphere where the fringe visibility reduces to almost zero. We also describe variations of this experiment with structured light beams, where the Pancharatnam phase leads to linear or nonlinear rotation of flower-pattern or spiral-shape interference fringes.
