Optical waveguide display technology is an important branch in the field of augmented reality display. Because optical waveguide has the exit pupil expansion function, it can greatly reduce the exit pupil size of relay optical system and realize light and miniaturization design, so it is widely used in head mounted display. In this paper, the imaging principle of optical waveguide optical system is analyzed, the internal light propagation law is studied, an optical waveguide configuration design based on two-dimensional expansion mode is proposed to realize two-dimensional expansion in both horizontal and vertical directions, and a miniaturized relay optical system is designed to reduce the size of the entrance pupil from 5mm × 3mm extended to 23mm × 20mm, the display system of large exit pupil is realized, and the continuity of exit pupil is verified by simulation calculation. This configuration can be used in the field of head mounted display system.
