[0023] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0024] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See also Figures 1 to 2 As shown, a naked-eye aerial imaging device of a cultural gallery in an embodiment of the present invention is provided at the top of the cultural gallery 100:

[0028] A naked-eye 3D display module 10 is used to display 3D images. The naked-eye 3D display module 10 includes a first multi-point naked-eye 3D display 11 and a second multi-point naked-eye 3D display 12 that are symmetrical to each other.

[0029] a negative refractive index optical element 20 for refracting the 3D images formed by the first multi-point naked-eye 3D display 11 and the second multi-point naked-eye 3D display 12 to different 3D viewpoints, respectively, to form three-dimensional stereoscopic images at two positions in the air. The negative refractive index optical element 20 is arranged at an angle to the naked-eye 3D display module 10 and includes a first transparent substrate 21, a first light waveguide layer 22, a second light waveguide layer 23, and a second transparent substrate 24, which are laminated in sequence;

[0030] The two multi-view imaging devices 30 are respectively used to display the three-dimensional stereoscopic images at two positions. The two multi-view imaging devices 30 are symmetrically arranged and are arranged at an angle to the negative refractive index optical element 20.

[0031] It's worth noting that the 3D image is projected directly in front of visitors via a negative-refractive-index optical element 20, achieving aerial imaging. Multi-viewpoint imaging devices 30 are arranged in pairs at the top of the corridor, so that as visitors advance, they can look diagonally upward at the ceiling and see a 3D image suspended beneath it. The multi-viewpoint imaging devices 30 provide multiple viewpoints, allowing multiple visitors to see clear 3D images from different angles. By adding a negative-refractive-index optical element 20 in front of the naked-eye 3D display module 10, the naked-eye 3D content is refracted. Using a refractive light path, the screen behind can be hidden, creating a more sci-fi look.

[0032] Furthermore, because the angle of refraction viewing is still less than 180 degrees, two multi-viewpoint imaging devices 30 are arranged in pairs, introducing the concept of a long corridor. Visitors approaching from either side of the corridor can see the aerial image pattern, ensuring that regardless of their direction, they are within the viewing angle range for optimal naked-eye 3D display. This ensures that users approaching from both sides of the corridor see the same aerial image. The two images are mirror images, so people approaching from different directions see the same image. Computer control software controls the paired display devices to synchronously display the same content.

[0033] See also Figures 3 to 5 As shown, specifically, the first optical waveguide layer and the second optical waveguide layer are respectively composed of a plurality of stacked reflection units.

[0034] Specifically, the angle between the negative refractive index optical element 20 and the naked eye 3D display module 10 is an acute angle. The acute angle can be 30°, 50°, or 60°.

[0035] Specifically, the negative refractive index optical element 20 is parallel to the top of the cultural corridor 100 .

[0036] Specifically, the multi-view imaging device 30 includes a substrate layer 31, an insulating layer 32, an adaptive optical adjustment layer 33, and a display panel 34, which are arranged in sequence. The substrate layer 31 includes a base material 311 and a conductive layer 312. The adaptive optical adjustment layer 33 includes a nanostructure layer 331 and an adjustment layer 332. The nanostructure layer 331 is composed of a plurality of nanostructures 3311 arrayed on a substrate 3312. The adjustment layer 332 includes an optical lens 3321 and a polarizer 3322. The display panel 34 is formed by an array of a plurality of first display areas 341 and a plurality of second display areas 342, wherein the first display areas 341 and the second display areas 342 of the array correspond to the nanostructures 3311 of the array.

[0037] In this embodiment, substrate 311 is made of a transparent material, such as glass. Conductive layer 312 is composed of a conductive material, such as a metal film. Nanobodies 3311 are formed by depositing a heat-sensitive material using electron beam lithography. The size and spacing of each nanobodies 3311 are controlled by controlling process parameters. The heat-sensitive material can be indium tin oxide.

[0038] In summary, the naked-eye aerial imaging device of the cultural corridor 100 in the above-mentioned embodiment of the present invention projects 3D images in front of the eyes of tourists through the optical element 20 with a negative refractive index, thereby realizing aerial imaging. The multi-view imaging devices 30 are arranged at the top of the corridor and arranged in pairs, so that when tourists move forward, they can see the 3D image suspended under the ceiling by looking up at the ceiling at an angle, wherein the multi-view imaging device 30 provides multiple viewpoints, so that multiple tourists can see clear 3D images at different angles. It can be seen that by adding a negative refractive index optical element 20 in front of the naked-eye 3D display module 10, the naked-eye 3D content is refracted, and the refractive light path is used to hide the screen behind, making it look more sci-fi.
