Paper Abstract

The conventional display can show only one screen, but it is impossible to enlarge the size of a screen, for example twice. Meanwhile the mirror supplies us with the same image but this mirror image is usually upside down. Assume that the images on an original screen and a virtual screen in the mirror are completely different and both images can be displayed independently. It would be possible to enlarge a screen area twice. This extension method enables the observers to show the virtual image plane and to enlarge a screen area twice. To enlarge the screen region twice, it is necessary to prepare a mirror. This mirror and the imaging plane of an original display must be placed at right angles to each other. Therefore, the mirrors take up much space in front of display. To solve this problem, we have developed a new reflective mirror using a holographic optical element.
