增强现实设备及其中所采用的光学系统和半反射镜技术方案

本公开涉及增强现实设备及其光学系统以及半反射镜，所述光学系统包括：图像投射光源；分光镜，所述分光镜具有靠近所述图像投射光源的分光面以及背离所述图像投射光源的透射面；以及半反射镜，所述半反射镜靠近所述分光面布置并且在所述图像投射光源发出的像源光被所述分光面所反射的光路上位于所述分光面的下游，所述分光镜布置成所述图像投射光源发出的像源光能够至少部分地被所述分光面朝向所述半反射镜反射，其中，所述半反射镜包括基片以及位于所述基片的远侧表面上的半反射膜。采用本发明专利技术的技术手段，可以增加光学系统的整体设计自由度，导致视场扩大并有利于人眼中的最终成像结果。

Augmented reality equipment and its optical system and semi mirror

The present disclosure relates to an augmented reality device, an optical system and a semi reflecting mirror, the optical system including: an image projection light source; a spectroscope, the spectroscope having a light dividing surface close to the image projection light source and a transmission surface away from the image projection light source; and a semi reflecting mirror, the semi reflecting mirror arranged close to the light dividing surface and emitting at the image projection light source The light path of the output image source light reflected by the light dividing surface is located at the downstream of the light dividing surface. The light dividing mirror is arranged so that the image source light emitted by the image projection light source can be reflected at least partially by the light dividing surface towards the semi reflecting mirror, wherein the semi reflecting mirror includes a substrate and a semi reflecting film on the far side surface of the substrate. By adopting the technical means of the invention, the overall design freedom of the optical system can be increased, the field of view can be enlarged, and the final imaging result of the human eye can be favorable.
