Problems solved by technology

[0012] However, in this device for realizing augmented reality, since the image light has undergone two reflections and transmissions of the beam splitter and one reflection and transmission of the curved half-mirror, the loss of the image light emitted from the plane image source is relatively large, and the light incident on the human body is relatively large. The image light of the eye is only 1 / 8 of the image light emitted from the plane image source, and the light utilization efficiency of the image light is low, resulting in insufficient image light intensity reaching the human eye, so that the interference light entering the human eye seriously reduces the augmented reality image. contrast, thereby degrading the user's augmented reality experience

Abstract

The present invention provides an augmented reality apparatus and device, and a method for implementation of augmented reality. The light utilization efficiency of image light can be improved. The augmented reality apparatus comprises an image source, a polarizing beam splitter, a wave plate module and a curved semi-reflecting mirror. The polarizing beam splitter is arranged in a direction of theimage light emitted by the image source, the wave plate module is arranged at one side of reflection light and / or transmission light of the polarizing beam splitter, and the curved semi-reflecting mirror is arranged at one side, far away from the polarizing beam splitter, of the wave plate module.

Description

technical field [0001] The present application relates to the technical field of Augmented Reality (AR, Augmented Reality), in particular, to an augmented reality device, device and method for realizing augmented reality. Background technique [0002] Augmented reality technology is a technology that presents and interacts with virtual reality and reality on the screen. By projecting virtual reality images and images of the actual environment into the eyes of users, users can achieve a fusion experience of virtual reality and reality. Among them, users wear devices that realize augmented reality, such as AR glasses, which is a common way for fusion experience. [0003] figure 1 It is a schematic diagram of the structure of an existing augmented reality device. Such as figure 1 As shown, the device includes: a plane image source 01, a lens 02, a beam splitter 03 and a curved half mirror 04, wherein, [0004] The plane image source 01 is arranged above the lens 02, in orde...
