    Aerial 3D Display using a Symmetrical Mirror Structure

Abstract:


    In the present study, we propose a new wide-viewing-angle aerial imaging display that can display aerial three-dimensional images to the surroundings. Aerial imaging has a strong visual impact, and significant efforts have been made to realize aerial imaging. In recent years, attention has been drawn to optical elements that realize retroreflective transmission, which makes it possible to easily project such images into the air. However, the viewing angle of the aerial image is narrow, and it is difficult for multiple people to simultaneously observe aerial images or to observe aerial images from all angles. Therefore, in the present study, by symmetrically arranging the mirrors at the end of the retro reflective optical transfer system, the maximum viewing angle of the aerial image is enlarged and observation from the entire circumference becomes possible.
