Problems solved by technology

Among them, the geometric optics scheme is the main idea. Compared with the diffraction scheme, it has the characteristics of mature technology, convenient device processing, and small assembly tolerance requirements. However, this type of scheme is limited by the overall size, weight, and price requirements of the light source device and the AR system. , there are common problems that size, price, field of view, performance, and observation distance cannot be taken into account, and the displayed content is easy to leak, and the confidentiality is poor; for myopia users, additional myopia lenses are required to be used together with the optical system
These disadvantages reduce the experience of using augmented reality wearable devices

The AR equipment can be adaptedto people with different myopia degrees through an adjusting system.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to an optical display system and AR equipment with folded optical paths. Background technique [0002] Augmented Reality (AR, Augmented Reality) is a technology that superimposes the real world and the virtual world through optical devices combined with computer technology. Interactive experience. Transmissive optical display system is one of the core technologies in the field of augmented reality. At present, wearable devices using enhanced display technology have been widely used in gaming, retail, education, industry, medical and other fields. [0003] At present, the transmissive optical display technology can be divided into geometrical optics schemes: Birdbath, ordinary reflective prisms, free-form surface prisms and other schemes, and arrayed optical waveguides and diffractive optical waveguides based on diffractive optics. Among them, the geometric opt...
