Fig. 2 Structured light recognition processes and capabilities. a Input modes are virous structured light: (ⅰ) HG44 mode, (ⅱ) LG10,2, (ⅲ) interferogram of VB and gaussian beam [87], (ⅳ) distorted OAM mode [88], (ⅴ)SU(2)[7], (ⅵ) OAM modes with fractional topological charge l = 1.28 [89], (ⅶ) HG modes superposition [100], (ⅷ) multiplexed OAM beam [98], (ⅸ) vector vortex beam [94], (ⅹ) phase distribution of OAM mode with turbulence [115], (xi) speckle patterns. b The ML networks contain CNN [94], opto-electronic neural network [99], D2NN [103]. c Recognition results are different recognition results: (i) the prediction of OAM angular index [85], (ii) OAM complex spectrum [98], (iii) recognition of distorted OAM mode [88], (iv) recovered phase of OAM mode after phase compensation[115].
