With the development of imaging display technology, the requirements for imaging characteristics are continuously increasing. The air imaging technology is that light emitted from an object to be projected arranged on one side of an optical lens is reflected by a mirror surface in the optical lens and simultaneously transmits through a plane of the optical lens, so that a mirror image of the object to be projected is imaged as a real image in a space on the other side of the optical lens. However, the imaging of the conventional optical lens structure is limited by the imaging angle or imaging direction, so that the structure with aerial imaging can only see aerial images at one angle within the effective viewing angle range when viewed from different angles, and cannot see aerial images at other angles.

21 and 22, the dihedral angle optical waveguides 2 are aligned to be arranged in an array, the

orthogonal reflection surfaces

21 and 22 are perpendicular to the inclined plane 3 of the wedge-shaped panel 1, and inner angles of the

orthogonal reflection surfaces

21 and 22 face in the same direction. The dihedral angle light guide 2 is focused toward a predetermined point, and the scattered light emitted from any point light source, planar light source and stereoscopic light source is focused again at the same position on the other side of the lens after passing through the lens of the special structure, as shown in fig. 5 and 6.

As shown in fig. 4, two

orthogonal reflection surfaces

21 and 22 of the dihedral angle light waveguide 2 are respectively provided with a reflection layer 4 for totally reflecting light.

Fig. 5 shows the working principle of the light path:

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.
