Abstract

This work presents an augmented reality display consisting of two freeform lenses. The first lens is composed of two aspherical polished surfaces and one plane surface, while the second lens acts as a compensator to allow distortion-free viewing of the surrounding area. One benefit of this design is the large size of the exit pupil, reaching up to 12 mm, and the low distortion value of 1.63 %. The optics has a thickness of 22 mm and is compatible with 0.49-in. diagonal displays. The field of view is limited to 28°, which is sufficient for various augmented reality applications.

为 AR 显示屏设计具有大出口瞳孔的自由形态元件

该作品展示了一种由两个自由形态透镜组成的增强现实显示屏。第一个透镜由两个非球面抛光表面和一个平面组成，而第二个透镜则作为补偿器，可以无畸变地观察周围区域。这种设计的优点之一是出口瞳孔大，可达 12 毫米，畸变值低，仅为 1.63%。光学器件的厚度为 22 毫米，可与对角线为 0.49 英寸的显示器兼容。视场角限制在 28°，足以满足各种增强现实应用的需要。
