中国科学技术大学，代顿大学，上海科技大学利用HDSLM64R进行涡旋光束拓扑电荷检测实验，该论文发表于Applied Optics Vol. 56, Issue 16, pp. 4868-4872 (2017) 

We demonstrate a new method to detect the vortex beams carrying orbital angular momentum by a sectorial screen. When the sectorial screen is illuminated by optical vortex beams, the far-field diffraction pattern can be used to visually determine the modulus and sign of topological charges. We also prove that center alignment is not strictly required. The experimental results agree well with the simulated results.
