A Micromirror Array Plate (MMAP) has been proposed as a type of aerial display that allows users to directly touch the floating image. However, the aerial images generated by this optical element have a limited viewing angle, making them difficult to use in face-to-face interactions. Conventional methods enable face-to-face usability by displaying multiple aerial images corresponding to different viewpoints. However, because these images are two-dimensional, they cannot be displayed at the same position due to the inherent characteristics of MMAP. An omnidirectional 3D autostereoscopic aerial display has been developed to address this issue, but it requires multiple expensive and specially shaped MMAPs to generate aerial images. To overcome this limitation, this study proposes a method that combines a single MMAP with integral photography (IP) to produce 3D aerial images with depth while reducing image misalignment. The experimental results demonstrate that the proposed method successfully displays a 3D aerial image using a single MMAP and reduces image misalignment to 1.1 mm.
微镜阵列板（MMAP）已被提议作为一种空中显示器，它允许用户直接触摸浮动图像。然而，由这种光学元件生成的空中图像视角有限，使其难以用于面对面交互。传统方法通过显示对应于不同视点的多个空中图像来实现面对面可用性。然而，由于这些图像是二维的，由于MMAP的固有特性，它们不能显示在同一位置。为了解决这个问题，已经开发了一种全向3D自动立体空中显示器，但它需要多个昂贵且形状特殊的MMAP来生成空中图像。为了克服这一限制，本研究提出了一种将单个MMAP与积分摄影（IP）相结合的方法，以产生具有深度的3D空中图像，同时减少图像错位。实验结果表明，所提出的方法成功地使用单个MMAP显示了3D空中图像，并将图像错位减少到1.1毫米。
