| 摘 要： | 平视显示系统是一种目前普遍运用于航空器上的飞行辅助器,它能使飞行员不用低头就可以看到仪表上的重要信息.针对传统平视显示系统体积大、生产成本高等不足,提出一种基于二维微扫描镜的平视显示系统.通过对二维微扫描镜的振动频率与平视显示图像的稳定性、分辨率、刷新率之间关系的分析研究,初步实现基于二维微扫描镜的平视显示系统的搭建,并成功完成一个常见标志的成像,证明基于二维微扫描镜的平视显示系统的可行性.

| Abstract: | HUD (Head-up Display) is a flight support device which has been widely used in aircraft. Important information on the instruments could be observed by pilots without lower their heads. A 2D micro scanning mirror-based HUD is presented in this paper due to the shortcomings of conventional HUD such as great volume and high cost. Through analyzing the relationship among oscillation frequencies of 2D micro scanning mirror, resolution, refresh rate and stability of HUD pattern, a prototype of HUD has been built successfully to project a common symbol. The projected image proves the feasibility of 2D scanning mirror-based HUD. |
