Zusammenfassung:The invention discloses a vortex electron modal identification system, method and device and electronic equipment. The system comprises a vortex electron generation module, a diffraction amplification module, an image receiving and collecting module, a data processing and recognition module, a training data preparation sub-module, an artificial intelligence model training sub-module and a modal identification module. Cyclotron electrons generated by the vortex electron generation module are coupled with the orbital angular momentum to generate vortex electron beams carrying different modes of OAM (orbital angular momentum); the diffraction amplification module diffracts and amplifies the vortex electron beam. The image receiving and collecting module is used for receiving the vortex electron beam subjected to diffraction amplification and collecting an OAM field intensity distribution image; the data processing and identification module receives the OAM field intensity distribution image and carries out OAM m
