Problems solved by technology

On the one hand, the existing imaging technology mainly uses lens imaging, which is mainly limited by the field of view and aperture. It has optical aberrations such as spherical aberration, coma, astigmatism, field curvature, distortion, and chromatic aberration. The field of large-aperture imaging display is relatively limited
On the other hand, most of the existing naked-eye 3D display technologies are based on adjusting the parallax of the left and right eyes to achieve 3D perception, rather than the actual 3D display technology.
And holographic imaging technology, the production cost is high

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 ...

Abstract

The invention provides a multi-row multi-column equivalent negative refractive index flat lens comprising a pair of glass windows respectively having two optical surfaces, and an optical waveguide assembly arranged between the two glass windows; the optical waveguide assembly comprises a multi-row multi-column rectangular optical waveguide array obliquely arranged in 45 degrees, and an edge optical waveguide arranged on the periphery of the rectangular optical waveguide array; single rectangular optical waveguides in each row and / or column of the rectangular optical waveguide array are same insizes. The flat lens is reconstructed by special precision microstructures; the multi-row multi-column rectangular optical waveguide array and the peripheral triangle optical waveguide enable two-dimension or three dimensional light sources to directly realize true holographic image in the air in real images.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an equivalent negative refractive index plate lens for realizing air imaging. Background technique [0002] With the development of imaging display technology, the requirements for imaging characteristics are constantly improving. On the one hand, a higher resolution is required to ensure the clarity of the observed picture while meeting the requirement of small distortion. On the other hand, it is required to have three-dimensional stereoscopic display characteristics, and at the same time, it has requirements for naked-eye three-dimensional holographic display. On the one hand, the existing imaging technology mainly uses lens imaging, which is mainly limited by the field of view and aperture. It has optical aberrations such as spherical aberration, coma, astigmatism, field curvature, distortion, and chromatic aberration. Large-aperture imaging shows a relatively limited fiel...
