An approach based on the two-channel moiré deflectometry has been used to measure both wavefront and transverse component of the Poynting vector of an optical vortex beam. Generated vortex beam by the q-plate, an inhomogeneous liquid crystal cell, has been analyzed with such technique. The measured topological charge of generated beams are in an excellent agreement with theoretical prediction.
一种基于双通道莫尔偏折术的方法被用于测量光涡旋光束的波前和光强横向分量。该技术分析了由 q 板（一种各向异性液晶盒）产生的涡旋光束。所测量的产生光束的拓扑电荷与理论预测非常吻合。
