Abstract:
A multidimensional encoding method through mode, phase, and intensity is demonstrated for superimposed OAM beam. Decoding of the camera-captured images is realized by the trained support vector machine algorithm. Under the 10-2 m time-varying phase turbulence, an image-transmission accuracy of 99.38% can be achieved.
