Embodiment 1

[0027] Such as Figure 1-2 As shown, an augmented reality optical system that can improve ghost images and ghost images includes a human eye 10 and a lens group 20. The lens group 20 includes a light source module 21, a first curved prism 22, and a second curved prism 23. The first curved prism The curved prism 22 and the second curved prism 23 are sequentially arranged between the light source module 21 and the human eye 10, the first curved prism 22 includes a first optical curved mirror 221 and a first prism 222, and the second curved prism 23 includes a second optical The curved mirror 231 and the second prism 232 form an image plane 30 on the first curved prism 22 .

[0028] The connections between the first prism 222 and the first curved optical mirror 221 , between the first prism 222 and the second prism 232 , and between the second prism 232 and the second curved optical mirror 231 are glued.

[0029] The curved surface of the first optical curved mirror 221 faces th...

Embodiment 2

[0041] Such as figure 1 , 3 As shown, an augmented reality optical system that can improve ghost images and ghost images includes a human eye 10' and a lens group 20, and the lens group 20 includes a light source module 21', a first curved prism 22' and a second curved prism 23 ', the first curved prism 22' and the second curved prism 23' are sequentially arranged between the light source module 21' and the human eye 10', the first curved prism 22' and the second curved prism 23' are glued and connected, the second An image plane 30 is formed on a curved prism 22'.

[0042] In the direction from the human eye 10' to the image plane 30, the lens group 20 has a trapezoidal structure, and the slope design is used on both sides of the prism group to reduce the reflection of stray light entering the human eye 10' through the two sides, effectively improving the seriousness of most products. In addition, the overall structure is trapezoidal, which effectively utilizes the optical ...

Abstract

The invention discloses an augmented reality optical system capable of improving ghost images, which comprises a human eye and a lens group, wherein the lens group comprises a light source module, a first curved surface prism and a second curved surface prism, the first curved surface prism and the second curved surface prism are sequentially arranged between the light source module and the humaneye, the first curved surface prism and the second curved surface prism are connected in a glued manner, and the lens group is of a trapezoidal structure. The augmented reality optical system effectively improves a ghost image phenomenon. Meanwhile, the augmented reality optical system is simple in structure and high in imaging brightness.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an augmented reality optical system capable of improving ghost images and ghost images. Background technique [0002] Augmented Reality (AR for short), which is a new technology that "seamlessly" integrates real world information and virtual world information, not only shows real world information, but also displays virtual information at the same time. The information complements and superimposes perfectly in the eyes of users. However, most of the existing augmented reality glasses have problems such as ghost images, low imaging brightness, and complex structures. The ghost image is an additional image generated near the focal plane of the optical system due to the reflection of the lens surface. Its brightness is generally dark and staggered from the original image. The existence of these problems not only affects the quality of the product itself, but also makes consumers ...
