Augmented reality display system based on diffraction integrator

The utility model discloses an augmented reality display system based on a diffraction integrator, and belongs to the technical field of augmented reality display. The device comprises a diffraction integrator which is composed of an ultraviolet light curing/thermal curing resin layer with a surface embossment diffraction grating and is used for reflecting a virtual image to human eyes; the diffraction integrator bearing substrate is used for bearing the diffraction integrator; the diffraction integrator bearing substrate is transparent or partially transparent; and the optical-mechanical projector is 5-60mm away from the center of the diffraction integrator, is used as an image display source and is used for projecting the virtual image to the diffraction integrator. The pair of glasses has the light and thin form of daily glasses, can be completely compatible with the daily glasses, has low manufacturing cost and high flexibility, can be copied on a large scale, and is suitable for industrial production. 本实
