Abstract:
In this study, we propose a method to produce a simple 3D aerial image display with a wide viewing angle. In recent years, research on aerial imagery has been actively evolving. However, in order to create a 3D aerial image with a wide viewing angle, complex and large-scale devices are still required. In the present study, the visual field of a retro-transmissive optical system is widened by a symmetric mirror structure that also enables multiple 3D images to be seamlessly coupled midair to form a wide viewing angle 3D display. As a result, a viewing angle approximately three times that of the conventional system is realized using only simple optical systems.
