With the advancement of the information society, AR glasses have attracted attention as core devices for integrating virtual and real spaces. Among them, waveguide-based AR glasses have been actively studied because they can achieve both a wide field of view and high see-through performance. In particular, approaches using two-dimensional diffraction gratings offer high design flexibility. In this study, we propose a two-dimensional diffraction grating based on a triangular pyramid structure to enable control of the optical output distribution and flexible design of output diffraction gratings.
