Abstract

We proposed a new type of dihedral corner reflector array (DCRA) called “radially arranged DCRA”. Our radially arranged DCRA could display a floating, three-dimensional image with a wide viewing angle without producing virtual images because dihedral corner reflectors were radially arranged for the designed paths of rays. In this research, we designed a reflector array pattern and evaluated the viewing angle of the floating image displayed by our radially arranged DCRA. During evaluation, we measured the reflection ratio of the radially arranged DCRA and demonstrated a floating image. Compared with a conventional DCRA, our radially arranged DCRA could expand the viewing angle from ± 30° to ± 90° without producing virtual images.
