Abstract

The invention provides an augmented reality display optical system and augmented reality glasses. The augmented reality display optical system includes a light source module, a light guide module, a transparent transmissive spatial light modulator and an afocal meniscus mirror that converts plane waves into spherical waves. The light guide module includes horizontal light guides and vertical light guides. The afocal meniscus mirror includes a transmissive and reflective film. The light source module is located on the incident light path of the vertical light guide, the horizontal light guide is located on the outgoing light path of the vertical light guide, the spatial light modulator is located on the outgoing light path of the horizontal light guide, and the afocal meniscus mirror is located on the outgoing light path of the spatial light modulator. The spatial light modulator of the augmented reality display optical system does not need to be placed at the near focal plane of the afocal meniscus mirror, and has a compact structure, small size, and light weight; and based on the principle of retinal imaging, it can clearly image images in the entire display field of view , myopia or hyperopia users can clearly receive the image information to be displayed without wearing correction glasses.

Description

technical field [0001] The invention relates to the technical field of optical display, in particular to an augmented reality display optical system and augmented reality glasses. Background technique [0002] At present, the augmented reality display optical system generally places the display screen at the focal plane position of the focusing lens (such as a spherical lens or an aspheric lens or a Fresnel lens), and uses a semi-reflective and semi-transparent plane mirror, and the in-focus point objects pass through the focusing lens The resulting enlarged virtual image is transmitted to the human eye through the semi-reflective and semi-transparent plane mirror, and the enlarged and upright virtual image of the display screen is projected in front of the user's eyes, while the external ambient light is received by the human eye through the semi-reflective and semi-transparent plane mirror, realizing the real world Enhanced display. The augmented reality display device ad...
