Orbital angular momentum has attracted a lot of attention due to its potential to increase communication capacity. However, the recognition of orbital angular momentum has always been a difficult problem. This paper proposes an orbital angular momentum recognition method based on diffraction neural network, and the simulation is done with CST software. The good results were obtained.
