We present a unique method for experimentally generating multiple vortices by way of a devil's vortex lens combined with a Fresnel lens using a spatial light modulator. These lenses have the multifocal properties of fractal zone plates combined with the orbital angular momentum of a spiral phase plate and can be tailored to fit within a small space on an optical bench. Results are presented alongside numerical simulations, demonstrating the robust nature of both the experimental method and the predictive power of the Huygens-Fresnel wavelet theory.
我们展示了一种独特的方法，通过使用空间光调制器，将恶魔涡旋透镜与菲涅耳透镜相结合，以实验方式产生多个涡旋。这些透镜具有分形波带片的多焦点特性，并结合了螺旋相位板的轨道角动量，且可以进行定制，以适配光学平台上的小空间。同时还给出了与数值模拟结果相对比的实验结果，证明了该实验方法的稳健性以及惠更斯-菲涅耳小波理论的预测能力。
