Abstract

We have developed a new optical device and aerial imaging display system with that device. The system has features that the pop-out distance of the aerial image is long and there is no need for a space having the same distance as the pop-out distance on the back side of the optical device. The optical device is a retro-reflective mirror array by arranging corner reflectors in strip shape. We have designed a layout of corner reflectors to image a real image at the designed depth by changing angles of the corner reflectors depending on the location. Thus, it has retroreflective characteristics in the horizontal direction of the optical device and specular reflection characteristics in the vertical direction.
