This paper presents a shadowless projection mapping system for interactive applications in
which a target surface is frequently occluded from a projector with a user's body. We …

Ray tracing, combined with ideal retroreflection and mathematical simulation methods, has
been used to design aerial imaging systems based on retroreflection. Although aerial …

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 …

Deflectometry is a key component in the precise measurement of specular (mirrored)
surfaces; however, traditional methods often lack an end-to-end approach that performs 3D …

Digital micromirror devices (DMD) have gained significant attention in various scientific and
industrial domains due to their potential for spatial light and laser modulation. However …

Although it is beneficial to use an optical simulator to design a mid-air imaging system, the
use of a simulator requires optical knowledge, and it cannot be handled by non-specialists …

This paper presents a mid-air imaging optical system consisting of two dimensionally
arranged truncated cylindrical optical elements. The proposed system aims to reduce the …

In this study, we propose an approach to display a distortion-free mid-air image inside a
transparent refractive object and on a curved reflective surface. We compensate for the …

Mid-air images are CG visuals that float in real space and can be observed without using
any devices. Owing to the unique display of mid-air images, a virtual reality (VR) simulation …

To develop optical systems for mid-air images, several methods have been proposed that
reproduce them in an application simulating their behavior. However, most of these methods …
