This paper reports a micromirror-based real image laser automotive head-up display (HUD), which overcomes the limitations of the previous designs by: (1) implementing an advanced display approach which is able to display sharp corners while the previous designs can only display curved lines such as to improve the display fidelity and (2) Optimizing the optical configuration to significantly reduce the HUD module size. The optical design in the HUD is simulated to choose the off-the-shelf concave lens. The vibration test is conducted to verify that the micromirror can survive 5 g. The prototype of the HUD system is fabricated and tested.

基于微镜的实像激光汽车平视显示器

本文报告了一种基于微镜的实像激光汽车平视显示器（HUD），它通过以下方式克服了先前设计的局限性：（1）实施了一种先进的显示方法，该方法能够显示锐角，而先前的设计只能显示显示曲线，以提高显示保真度；（2）优化光学配置，以显着减小HUD模块的尺寸。对HUD中的光学设计进行了仿真，以选择现成的凹透镜。进行振动测试以验证微镜能否幸存5 g。HUD系统的原型已制造并经过测试。
