Abstract

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 surface that 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 eyebox defined within a cabin of the vehicle.
