We have realized a new optical system to form multiple aerial images by use of thin optical components. The proposed optical system is based on aerial imaging by retro-reflection (AIRR). The aerial image formed by AIRR is visible over a wide viewing angle without using 3D glasses. In addition to AIRR, we have introduced a technique called infinity mirror in which a mirror and a half mirror are arranged in parallel to form multiple virtual images of a single light source. By combining AIRR and infinity mirror, multiple images are formed in mid-air. By placing a retro-reflector obliquely outside the infinity mirror, our proposed optics improves brightness of the aerial images by placing.

使用无限远反射镜和斜后向反射镜进行多次航空成像

我们实现了一个新的光学系统，通过使用薄的光学元件来形成多个航拍图像。所提出的光学系统基于逆反射（AIRR）的航空成像。无需使用 3D 眼镜，AIRR 形成的航拍图像可在宽视角下可见。除了AIRR之外，我们还引入了一种称为无限远反射镜的技术，其中反射镜和半反射镜平行排列以形成单个光源的多个虚像。通过结合AIRR和无限远镜，在半空中形成多个图像。通过将后向反射器倾斜放置在无限远镜外，我们提出的光学器件通过放置来提高航拍图像的亮度。
