| description | The embodiment of the invention discloses a multi-coupling diffraction optical waveguide, a design method thereof and near-to-eye display equipment. The multi-coupling-in diffraction optical waveguide comprises a plurality of one-dimensional coupling-in gratings and a two-dimensional coupling-out grating. The design method comprises the steps that the period and the period arrangement direction of one of the one-dimensional coupling-in gratings and the two-dimensional coupling-out gratings are determined; according to the period of one of the plurality of one-dimensional coupling-in gratings and the plurality of two-dimensional coupling-out gratings, determining the period range of the other one; according to a preset design condition, the period of the one-dimensional coupling-in grating corresponding to each wavelength is selected in the period range, and the directions and positions of the one-dimensional coupling-in grating and the two-dimensional coupling-out grating corresponding to each wavelength are |
