| 摘 要： | HMD光学系统的设计非常具有挑战性。本文介绍了HMD光学系统的工作原理和一般组成。理想的HMD光学系统应该重量轻、体积小。为满足这些要求，文中描述了改进传统的HMD光学系统的两种方法，一种是用头盔护目镜和FFS棱镜重新构造HMD光学系统，另一种是用HOE和BOE替代传统的光学元件。这些模式比传统HMD光学系统优越，而且能使HMD光学系统体积小，重量轻。

| Abstract: | The design of HMD optical system is very challenging. This paper briefly introduces the work principle and the general construction of HMD optical system. A perfect HMD optical system should be light weight and compact. To comply with these requirements, two methods are described to improve the conventional HMD optical system in this paper. The first one is to reconstruct a superior HMD optical system with helmet visor and Free Form Surface (FFS) prism. And the second one is to substitute the conventional optical elements with HOE and BOE. These models have many advantages over conventional optical systems and make HMD optical system compact and light weight. |
