Single-line multi-row equivalent negative refractive index flat lens

Abstract

The invention provides a single-line multi-row equivalent negative refractive index flat lens, which comprises a pair of glass windows with two optical surfaces and two groups of light waveguide arrays positioned between the two glass windows, wherein the optical waveguide array is formed by single-line multi-row light waveguides being in 45-degree inclined arrangement and having the rectangular cross section; the waveguide directions of the mutually corresponding parts of the two groups of light waveguide arrays are vertical to each other. Through the reconstructed plane lens of the special precise microscopic structure, the single-line multi-row light waveguides with the rectangular cross section are used for forming an array structure; two-dimensional or three-dimensional light sourcesdirectly form solid images in the air to realize the real holographic image.

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...

AI Technical Summary

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
