Aerial 3D Imaging by Retroreflective Mirror Array

Takafumi Koike (Hosei Univ.)  and Yasushi Onishi (OPTCERAMICS, Ltd.)

We have developed a retroreflective optical device (Oz panel) for realizing an aerial imaging display with a long protruding distance.

Optical Characteristics

Principle

We arrange a rectangular corner reflector array like a figure. By changing the aspect ratio of the corner reflector array depending on the in-plane position of the optical device, we can realize aerial imaging with a long focal length (jump-out amount).
