Abstract
We proposed a new type of dihedral corner reflector array (DCRA) called “radially arranged DCRA”. Our radially arranged DCRA could produce a seamless floating image with a wide viewing angle and without producing virtual images because of designed optical paths of reflected rays. We designed the arrangement of reflectors and fabricated the radially arranged DCRA by photolithography process using SU-8 3010. Using the fabricated DCRA, we measured reflection ratios of conventional and radially arranged DCRA and demonstrated floating images. The radially arranged DCRA could produce a seamless floating image with viewing angle of $\pm 90^{\circ}$ and did not produce virtual images.
