Embodiment Construction
[0020] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0021] Such as figure 1 As shown, the equivalent negative refractive index plate lens includes a first glass window 1 , two groups of optical waveguide components 2 and a second glass window 3 from the object side to the image side in sequence. Both the first glass pane and the second glass pane have two optical surfaces, and are mainly used to protect the optical waveguide assembly.
[0022] Such as figure 2 As shown, the optical waveguide assembly includes multiple rows and columns of rectangular optical waveguide arrays arranged obliquely at 45°, and edge optical waveguides placed around the periphery of the rectangular optical waveguide arrays so that they are spliced into a lens.
[0023] Each column and / or row of the rectangular optical waveguide array has the same size of a single rectangular optical waveguide, and the material of ...
