The invention discloses an augmented reality display device. The display device comprises a light source output device, an MEMS galvanometer, a transmissive and reflecting device and a light reflection convergence device. The MEMS galvanometer is arranged at the focal point of the light reflection convergence device, or the optical axis of the light reflection convergence device and is away from the focal point. The light source output device is used for outputting light modulated according to image information; the light output by the light source output device is reflected by the MEMS galvanometer, and is transmitted by the transmissive and reflecting device to the light reflection convergence device; after being gathered by the light reflection convergence device, the light is reflected to the transmissive and reflecting device; and finally, the light is reflected to the human eye by the transmissive and reflecting device to form a projected image. Ambient light is transmitted to the human eye by the transmissive and reflecting device to form an ambient image. Since the MEMS galvanometer is arranged at the focal point of the light reflection convergence device, or the optical axis of the light reflection convergence device and is away from the focal point, light path between the MEMS galvanometer and the light reflection convergence device is guaranteed, and view field of the augmented reality display device is enlarged obviously.
Description
technical field [0001] The present invention relates to the field of augmented reality, in particular to an augmented reality display device. 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 .
