Summary:A wireless optical encryption communication method using vortex light scrambling includes the following steps: generating N orbital angular momentum topological charge numbers corresponding to N Gaussian light source carrier waves; converting the N separated Gaussian light source carrier waves into vortex beams, each with N encoded orbital angular momentum to obtain N vortex optical signals; generating an encrypted pairing combination; when each input terminal receives a corresponding input vortex optical signal, outputting the corresponding input vortex optical signal to the output terminal corresponding to the input terminal according to the encrypted pairing combination; each modulator performing modulation according to the vortex optical signal output by the corresponding output terminal and one of the N bit data to generate and output an optical modulation signal; performing multiplexing processing on the N optical modulation signals to generate an optical multiplexing output signal.
