Abstract:
1. A three-dimensional image projector, comprising: a transparent display medium within which fluorescent substances are dispersed, said fluorescent substances being dispersed for performing fluorescent light-emission of visible light by irradiation with a laser beam of invisible light; first-laser-beam scanning means for scanning inside of said transparent display medium by deflecting a first laser beam, said first laser beam being used for exciting said fluorescent substances; and second-laser-beam scanning means for scanning said inside of said transparent display medium by deflecting a second laser beam, said second laser beam being used for exciting said fluorescent substances, wherein a stereoscopic image is formed in such a manner that excitation of said fluorescent substances, which is caused by said irradiation with said first laser beam, and excitation of said fluorescent substances, which is caused by said irradiation with said second laser beam, are superimposed on each other, thereby performing said fluorescent light-emission, and forming said stereoscopic image, said stereoscopic image being formed at a scanning intersection point of said first laser beam and said second laser beam inside said transparent display medium.
