As shown in fig. 7, the 360-degree aerial imaging device according to the second embodiment includes two optical waveguide array units 5 and two objects to be projected O, and the two objects to be projected O are disposed so as to correspond to the two optical waveguide array units 5. The dihedral angle optical waveguides 2 of the two optical waveguide array units 5 are all oriented to the point of the upper-air focusing imaging of the centers of the two optical waveguide array units 5, the inclined angle 3 on the wedge-shaped panel 1 is adjusted, and the positions and orientations of the two objects to be projected O are adjusted to make the images P imaged in two directions coincide, and the light emitted from the objects to be projected O is reflected by the dihedral angle optical waveguides 2 of the optical waveguide array units 5 and simultaneously transmits the plane of the optical waveguide array units 5, so that the mirror image of the objects to be projected O is imaged as a real mirror image P in the space on the other side of the optical waveguide array units 5.

In addition, the number of the optical waveguide array units 5 constituting the 360-degree aerial imaging device is arbitrary, and the larger the number thereof, the more natural the continuity of the image in switching of the optical waveguide array units 5 which image an aerial image by viewpoint movement becomes, and the problem due to the primary reflected light in the optical waveguide array units 5 is not easily caused, and the optical waveguide array constituting the 360-degree aerial imaging device may be made up of several optical waveguide array units 5, or a plurality of optical waveguide array units 5 may be provided on one transparent plate.

As shown in fig. 7, a light shielding plate 8 is provided between the two objects to be projected O. By providing such a light shielding plate 8, an unintended image can be prevented from being viewed as being imaged at an unintended position. Further, a viewing angle adjusting film 9 is attached to the upper surface of each optical waveguide array unit 5 so as to transmit light in each specific direction and block light in the other specific direction. Specifically, the optical film 9 prevents the light emitted from the object O from directly passing through the light guide array units 5 from reaching the viewpoints V1 and V2, thereby preventing the object O from being directly observed from the viewpoints V1 and V2 by the light guide array units 5, while only transmitting the light reflected twice by the light guide array units 5 and passing through the light guide array units 5, thereby allowing only the real image P of the object O to be observed from the viewpoints V1 and V2.

The scattered light emitted from any point light source, planar light source and stereo light source will be refocused and imaged at the same position on the other side of the lens after passing through the lens with the special structure, see fig. 5 and 6.

on the micrometer structure, a reflecting layer mirror surface structure which is orthogonal with each other is used for orthogonal decomposition of any optical signal, an original signal is decomposed into two paths of mutually orthogonal signals of a signal X and a signal Y, the signal X is totally reflected on the mirror surface according to a reflection angle which is the same as an incident angle on a first physical layer, the signal Y is kept parallel to the first physical layer at the moment, after passing through the first physical layer, the signal Y is totally reflected on the mirror surface according to a reflection angle which is the same as the incident angle on a second physical layer surface, and a reflected optical signal which is formed by the reflected signal Y and the signal X is mirror-symmetrical with the original optical signal. Therefore, the light rays in any direction can realize mirror symmetry through the lens, the divergent light of any light source can be refocused and imaged at a symmetrical position through the lens, the imaging distance is the same as the distance between the holographic reflection layer and the light source, the imaging is carried out at equal distance, the image is positioned in the air, a specific carrier is not needed, and the real image is directly imaged in the air. Therefore, the image in the space seen by the user is the light emitted by the actual object.

After the original light source passes through the imaging lens structure, the above processes occur on the imaging lens structure, the focused and imaged incident angles are beta 1, beta 2, beta 3, beta 4 ….. beta.n, and the distance L between the image and the optical lens structure, so that the image is imaged on the optical lens structure

The viewing angle is 2 times max (beta) at the equal distance L from the original light source, so if the size of the lens is small, the image can be seen only at a certain distance from the front; the lenses are combined together to focus the light beams guided out by the lenses towards a specified point, so that people can view aerial images within the range of 360 degrees, and if the size of the plate is increased, a larger imaging distance can be realized, and the visual field rate is increased.
