Abstract

The invention provides a surface augmented reality planar waveguide optical device with the microstructure. According to the technical scheme, the device comprises an integrally formed main body, andthe surface of the main body is provided with an incident surface, a top surface, a bottom surface, a compensation surface, a microstructure surface and a resin microstructure layer; the main body iscomposed of optical resin, the incident surface is a free-form surface of the main body surface, the top surface is a section of plane of the main body surface, and the bottom surface is a plane of the main body surface and is parallel to the surface where the top surface is located; the compensation surface is a plane of the main body surface, the microstructure surface is a sunken surface of themain body surface, and the plane where the microstructure surface is located is parallel to the planes where the top surface and the bottom surface are located; the microstructure surface is composedof multiple same microstructure units, and each microstructure unit comprises a first microstructure unit surface and a second microstructure unit surface. The device has the advantages that the eyemovement range is larger, the structure is smaller and lighter, and mass production of intelligent glasses is enhanced more conveniently.

Description

Technical field [0001] The invention relates to the field of augmented reality technology, in particular to a curved surface augmented reality planar waveguide optical device with a microstructure. Background technique [0002] Augmented Reality (AR) is a technology that calculates the position and angle of the camera image in real time and adds corresponding images, videos, and 3D models. The goal of this technology is to put the virtual world on the screen. Real world and interact. This technique was proposed in 1990. With the improvement of CPU computing power in portable electronic products, it is expected that the use of augmented reality will become wider and wider. [0003] Augmented reality glasses (AR glasses) are an important expression method of augmented reality technology. There are various optical solutions in the prior art that can realize the display effect of augmented reality to varying degrees. [0004] The optical waveguide solution is one of the optical solut...
