Abstract
The utility model relates to a reflective AR glasses device. The display screen comprises a transparent display screen, a display screen driver and a curved surface semi-transmission and semi-reflection mirror, wherein the transparent display screen is arranged on one side close to human eyes and is connected with the display screen driver through a data line; the curved surface semi-transmission and semi-reflection mirror is arranged at one side far away from human eyes, so that the transparent display screen is positioned on the focal plane of the curved surface semi-transmission and semi-reflection mirror and is coaxially arranged with the curved surface semi-transmission and semi-reflection mirror; the optical image light beam presented on the transparent display screen passes through the curved surface semi-transmission semi-reflection mirror, a part of light is projected out, and a part of light is reflected to enter human eyes. The utility model discloses reduce among the AR glasses optical system moving part, improved optical system's stability, be favorable to the frivolousization of AR glasses.
Description
Technical Field
The utility model relates to an augmented reality's technical field, in particular to reflective AR glasses device.
Background
Augmented Reality (AR) is a technology that calculates the position and angle of a camera image in real time and adds corresponding images, videos, and 3D models. Virtual information is applied to the real world through a computer technology, and a real environment and a virtual object are superposed on the same picture or space in real time and exist at the same time.
For AR glasses, the volume of the optical imaging system directly determines the thickness and weight of the AR glasses, whereas the existing near-to-eye display optical module for AR glasses is generally complex in structure, large in volume and not high in stability.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a reflective AR glasses device compares and utilizes optical assembly AR glasses with the tradition, the utility model discloses a structure is fairly simple, stability characteristics such as relatively good.
The utility model provides a technical scheme that technical problem took does:
The utility model discloses a transparent display screen, display screen driver and curved surface semitransmission half-reflecting mirror. The transparent display screen is arranged on one side close to human eyes and is connected with the display screen driver through a data line; the curved surface semi-transmission semi-reflecting mirror is arranged on one side far away from human eyes, so that the transparent display screen is positioned on a focal plane of the curved surface semi-transmission semi-reflecting mirror and is coaxially arranged with the curved surface semi-transmission semi-reflecting mirror.
The optical image light beam presented on the transparent display screen passes through the curved surface semi-transmission semi-reflection mirror, a part of light is projected out, and a part of light is reflected to enter human eyes.
furthermore, the transparent display screen and the curved semi-transmission and semi-reflection mirror are fixed on the mirror bracket.
Furthermore, the transparent display screen is a transparent display screen with a polymer lens substrate.
Furthermore, the transparent display screen is made of transparent glass.
The utility model discloses reduce among the AR glasses optical system moving part, improved optical system's stability, be favorable to the frivolousization of AR glasses.

fig. 1 is a schematic structural diagram of an optical assembly of the reflective AR glasses of the present invention.
Detailed Description
The utility model discloses a: the display comprises a transparent display screen 1, a display screen driver 2, a mirror frame 3 and an optical element curved surface half-reflecting mirror 4. The transparent display screen is arranged on one side of the eye close to the transparent display screen, and the transparent display screen is positioned on the focal plane of the curved semi-transmission and semi-reflection mirror. The curved surface semi-transmission and semi-reflection mirror of the optical element is arranged at the outermost side and is coaxial with the transparent display screen.
The transparent display screen can generate an optical image with AR content, namely an AR image source viewed by a user, under the work of the display screen driver. The utility model discloses the transparent display screen that uses is transparent glass or polymer lens, also can make external true image light beam see through the display screen and get into people's eye when showing the AR image.
The optical element curved surface reflector is arranged on the outermost side, namely the side close to the outside, and the lens is a semi-reflecting and semi-transparent lens, so that on one hand, half of AR image light beams displayed on the transparent display screen are transmitted out, and half of the AR image light beams are reflected back. On the other hand, light beams emitted by images of external real objects can penetrate through the curved semi-reflecting lens and enter human eyes through the transparent display screen, so that the effect of virtual and real combination is achieved.
The working principle of the utility model is as follows:
Under the working condition of a display screen driver, the generated optical image with AR content is reflected to human eyes A through curved semi-reflecting mirror light beams; meanwhile, for an external real image B, half of the light beam passes through the curved semi-reflecting mirror, and is incident to the human eye A through the transparent display screen.
Compare in the optical element combination of traditional realization AR glasses, the utility model discloses simple structure, and stability is better.
The above description is only an embodiment of the present invention, but the technical features of the present invention are not limited thereto, and any changes or modifications within the technical field of the present invention by those skilled in the art are covered by the claims of the present invention.
