[0035] The present invention will be further described below in conjunction with implementation examples and accompanying drawings.
[0036] In order to make the purpose of the invention, the technical solution and its advantages clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.
[0037] see Figure 1-Figure 5 :
[0038] A method for generating elliptical vortex light with an amplitude modulation device. The method uses an amplitude-type imitation spiral photon sieve to generate elliptical vortex light. The structural schematic diagram of the amplitude-type imitation spiral photon sieve is as follows figure 1 As shown, the amplitude-type imitation spiral photon sieve includes a transparent medium substrate 1, an opaque metal film 2 and a spiral mesh structure 3, and the transparent medium substrate 1 is provided with the opaque metal film 2, so The spiral mesh struct...
