| Summary: | An optical system includes: a cylindrical waveguide having concentric inner and outer surfaces defining a common cylindrical axis; and an input optic arranged to receive light from the image source and to cause the light to enter the cylindrical waveguide such that at each incident point, the cylindrical waveguide has a plurality of light sources, all light rays originating from the same pixel of the image source are incident on the surface of the cylindrical waveguide at the same angle with respect to the surface normal and the same angle with respect to a plane orthogonal to the cylindrical axis so that the coupled light maintains its directional angle when propagating along the cylindrical waveguide. The optical system may be used to provide an optical display device that may form part of a head-mounted display.
一种光学系统，包括：圆筒状波导，该圆筒状波导具有限定共同圆筒轴线的同心的内侧表面和外侧表面；以及输入光学器件，该输入光学器件被布置成接收来自图像源的光并使光进入圆筒状波导，使得在每个入射点处，源自图像源的同一像素的所有光线以相对于表面法线的相同角度和相对于与圆筒轴线正交的平面的相同角度入射在圆筒状波导的表面上，从而耦入光在沿着圆筒状波导传播时保持其方向角。可以使用该光学系统来提供可以形成头戴 |
