Experimental measurements of the twirl and changes in the anisotropy of the constant intensity ellipse, and the rotation of the polarization singular lemon pattern a generalized vector-vortex beam experiences around the two foci due to the converging and diverging conical waves and in between, are presented and interpreted as being due to the universal form of the Gouy phase, φ(G)=mπ/2.
实验测量了常强度椭圆的扭转和各向异性变化，以及由于会聚和发散的锥形波以及它们之间的相互作用，偏振奇异柠檬花样的旋转，这些现象被解释为是由于普遍形式的古伊相位，φ(G)=mπ/2。
