Embodiment 1

[0058] The present invention analyzes the relationship between the imaging point in space and the physical display array through the pinhole imaging model, and proposes a design structure of a micro-optical system, which can realize that the central depth plane (CDP) is perpendicular to the physical display plane and forms a real image The floating display effect has a strong sense of technology and future. In addition, the 360-degree full-view 3D display can be realized by splicing and displaying, which effectively reduces the amount of data required to realize complex 3D scenes. And effectively eliminate the fatigue of human eyes watching.

[0059] When integrated imaging reproduces a 3D scene, there is only one image plane that is conjugate to the display panel. When the image plane of the reproduced 3D image deviates from this plane, the resolution will drop significantly. The plane that is conjugate with the display panel is called the Central Depth Plane (CDP for short)...

Embodiment 2

[0072] This technical solution realizes the formation of a real image of a two-dimensional floating display perpendicular to the horizontal plane in space. The structure of the optical components is as follows: Figure 14 As shown, in this embodiment, the micro-image array is placed on a wedge-shaped glass substrate with an inclination angle of ω, the plane formed by the micro-image unit array forms a small angle ω with the horizontal plane, and the plane formed by the micro-image unit and the micro-image unit array is The angle between them is 0, the micro-optical unit array is set as a plane, parallel to the horizontal plane and placed on the micro-image array in reverse, and a group of micro-ray refraction units are placed above the optical unit array to change the image through the lens. The direction of light propagation after modulation. In this embodiment, the micro-optical unit is preferably used as a lens, and the micro-image array adopts an ultra-high-resolution liqu...

Embodiment 3

[0078] This technical solution realizes the formation of a two-dimensional suspended real image perpendicular to the display plane in space. The micro-optical unit is a concave mirror array, which adopts a one-dimensional lens array arranged at non-equal intervals, and metal Al is evaporated on the surface of the lens as a reflector. layer, so that the lens array becomes a concave mirror array, such as Figure 17 As shown, there are m unit concave mirrors on each one-dimensional concave mirror.

[0079] In this embodiment, a transparent OLED display is preferably selected as the micro-image unit array, and the one-dimensional OLED display array is attached to the one-dimensional concave mirror array. Place n groups of such one-dimensional concave mirror arrays (as reflective layer 40) bonded with OLED displays in the base engraved with n inclined grooves, so that the plane of the OLED display array is parallel to the horizontal plane, and the focal plane of the concave mirrors...

Abstract

Disclosed in the invention is an integrated imaging optical system comprising an optical unit array and a micro image array. The optical unit array includes a plurality of micro optical units and enables points on a focal plane to be scattered at all directions in space. The micro image array includes a plurality of micro image units containing a plurality of pixel units; display image layers of the micro image units are located near the focal planes of the micro optical units; all micro image units cooperate with the corresponding micro optical units respectively and corresponding micro images are formed at a set interface. All pixels of all micro images are combined to form an integrated image. According to the invention, an effect of suspension displaying by being perpendicular to a physical display plane and being in a real image mode is realized; the good technological and futuristic effects are also realized. On the basis of the spliced displaying way, 360-degree full-view-angle tree-dimensional displaying is realized, thereby effectively reducing the data volume for realizing a complicated three-dimensional scene. And the fatigue feeling of watching by human eyes can be eliminated effectively.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and relates to an optical system, in particular to an integrated imaging optical system. Background technique [0002] Vision is the main way for human beings to perceive the world. About 80% of the information obtained by human beings comes from vision. For a long time, the main method of expressing visual information is still two-dimensional display. The traditional two-dimensional display technology loses the depth information of the real physical world, cannot accurately express the three-dimensional spatial relationship, and can only present the surface characteristics of objects at a single angle. This defect seriously hinders human beings' perception of the objective world. How to realize three-dimensional reproduction in real physical space has always been the goal that people are striving for. In order to truly describe the objective three-dimensional world, people try to use va...
