(EN) An input-coupler of an optical waveguide couples light corresponding to the image and having a corresponding FOV into the optical waveguide, and the input-coupler splits the FOV of the image coupled into the optical waveguide into first and second portions by diffracting a portion of the light corresponding to the image in a first direction toward a first intermediate-component, and diffracting aportion of the light corresponding to the image in a second direction toward a second intermediate-component. An output-coupler of the waveguide combines the light corresponding to the first and second portions of the FOV, and couples the light corresponding to the combined first and second portions of the FOV out of the optical waveguide so that the light corresponding to the image and the combined first and second portions of the FOV is output from the optical waveguide. The intermediate-components and the output-coupler also provide for pupil expansion.
(ZH) 光波导的输入耦合器将与图像相对应并且具有对应FOV的光耦合到光波导中，并且输入耦合器通过在朝向第一中间组件的第一方向上衍射与图像相对应的光的一部分，并且在朝向第二中间组件的第二方向上衍射与图像相对应的光的一部分，来将耦合到光波导中的图像的FOV分成第一部分和第二部分。波导的输出耦合器组合与FOV的第一部分和第二部分相对应的光，并且将与FOV的组合的第一部分和第二部分相对应的光耦合出光波导，使得与图像和FOV的组合的第一部分和第二部分相对应的光从光波导输出。中间组件和输出耦合器也提供光瞳扩展。
