The invention relates to image display technology, in particular to a device for rendering an augmented reality image and a system for realizing augmented reality display comprising the device. The device according to one aspect of the invention comprises: an optical waveguide lens; and a first two-dimensional grating array located on a surface of the optical waveguide lens; a second two-dimensional grating array located on the surface of the optical waveguide lens, wherein, positions of the first two-dimensional grating array and the second two-dimensional grating array on the surface of the optical waveguide lens are set so that larger edges of the two are opposite, wherein, the first two-dimensional grating array is configured such that rays incident on the first two-dimensional grating array expands to the entire first two-dimensional grating array on the one hand, and propagates to the second two-dimensional grating array on the other hand, wherein, the second two-dimensional grating array is configured such that rays propagating to the second two-dimensional grating array expands to the entire second two-dimensional grating array on the one hand, and emits from the optical waveguide lens on the other hand, wherein, the first two-dimensional grating array and the second two-dimensional grating array have the same period.
