We proposed and implemented an omnidirectional mid-air image optical system that
suppresses stray light and transmitted light. When micro-mirror array plates (MMAP) are …

In this paper, we propose a new approach to create a compact autostereoscopic aerial multi-
view display. It employs a transmission type retroreflector, ie a slit mirror array (SMA), and a …

In this paper, we describe AiRound, an optical system that displays mid-air images that can
be viewed from any direction. Mid-air images are touchable floating images formed by …

In this study, we have developed a novel method that enables the visualization of light rays
in the air and interaction with these rays. In this method, the first step involves illuminating …

ABSTRACT A mid-air image is an image that appears in space without a physical display
due to the geometric optical formation of light. Retro-transmissive plates (RT Plates) can …
