The disclosure provides an optical extender for vehicle heads up displays. The invention provides an apparatus and method for designing an optical extender for a vehicle heads up display (HUD). An example vehicle includes a windshield and a HUD system. The HUD system includes an image source to provide a projection image and a main mirror to project the projection image onto the windshield. The image source and the main mirror define a light path. The HUD system also includes an optical extender between the main mirror and the windshield. The optical extender has a multi-polynomial top surfacethat modifies light in the light path to, when the light in the light path intersects the windshield, create an optical path wherein a virtual image of the projection image is visible from an eyeboxdefined within a cabin of the vehicle.

    本公开提供了“用于车辆抬头显示器的光学扩展器”。用于设计用于车辆抬头显示器(HUD)的光学扩展器的设备和方法。一种示例性车辆包括挡风玻璃和HUD系统。所述HUD系统包括:图像源,所述图像源用于提供投影图像;以及主反射镜,所述主反射镜用于将所述投影图像投影到所述挡风玻璃上。所述图像源和所述主反射镜限定光路径。所述HUD系统还包括在所述主反射镜与所述挡风玻璃之间的光学扩展器。所述光学扩展器具有多项式顶表面,所述多项式顶表面修改所述光路径中的光以在所述光路径中的所述光与所述挡风玻璃相交时产生光学路径,其中所述投影图像的虚拟图像是可从限定在所述车辆的车厢内的眼箱看到的。
