Abstract

The invention discloses a near-to-eye display optical system. The near-to-eye display optical system includes an image source, a relay imaging lens group, a reflectible and permeable plane mirror and a reflectible and permeable concave mirror; image light outputted by the image source passes through the relay imaging lens group, and thereafter is reflected to the reflectible and permeable concave mirror through the reflectible and permeable plane mirror; after being amplified and reflected by the reflectible and permeable concave mirror, the image light is transmitted through the reflectible and permeable plane mirror and then is received by eyes; and external ambient light passes through the reflectible and permeable concave mirror and the reflectible and permeable plane mirror sequentially, and then is received by the eyes. According to the near-to-eye display optical system of the invention, the traditional optical devices are adopted to transmit the image light outputted by the image source to the eyes, since the traditional optical devices have the advantages of low dispersion in image light transmission, the accuracy of the color of a virtual image provided by the near-to-eye display optical system can be ensured; the loss rates of the image light entering the eyes are the same, so that the uniformity of the brightness of the virtual image can be ensured.

Description

technical field [0001] The invention relates to the field of augmented reality, in particular to a near-eye display optical system. Background technique [0002] Augmented Reality (English: Augmented Reality; abbreviation: AR) is a technology that uses virtual objects or information to enhance the reality of real scenes. Augmented reality technology is usually based on the real physical environment images obtained by image acquisition equipment such as cameras, through computer system recognition analysis and query retrieval, the virtual generated extended information or virtual scene display of associated text content, image content or image models, etc. In the real physical environment image, so that users can obtain related extended information such as annotations and descriptions of real objects in the real physical environment, or experience the three-dimensional and highlighted enhanced visual effects of real objects in the real physical environment .
