    • A volumetric imaging apparatus is energizable to form an image onto a display surface as an input to a monocentric catadioptric imaging apparatus having a light path for image-bearing light from the display surface, wherein the light path extends substantially symmetrically to a vertical plane that extends through a curved relay mirror and a curved primary mirror. The monocentric catadioptric imaging apparatus has reflective surfaces to fold the light path between the curved relay mirror and the curved primary mirror to condition the distribution of the image-bearing light in a horizontal direction. The light path of the monocentric catadioptric imaging apparatus directs light from the curved primary mirror toward a light input surface of a vertical pupil expander that has a light exit surface that is substantially orthogonal to the vertical plane. The light exit surface directs light through a free-form corrector for convergence and toward a windshield for display.
    • 体积成像装置可激励以在显示表面上形成图像,作为具有用于来自显示表面的图像承载光的光路的单中心反射折射成像装置的输入,其中光路基本对称地延伸到延伸的垂直平面 通过弯曲的中继镜和弯曲的主镜。 单中心反射折射成像装置具有反射表面,以折叠弯曲的中继反射镜和弯曲的主反射镜之间的光路,以调节图像承载光在水平方向上的分布。 单中心反射折射成像装置的光路将来自弯曲主反射镜的光引导到具有基本上垂直于垂直平面的光出射表面的垂直光瞳扩展器的光输入表面。 光出射面通过自由形式的校正器引导光束会聚并朝向挡风玻璃显示。
