Filed: 2006-02-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a three-dimensional video display method and apparatus capable of displaying a uniform, clear, three-dimensional video without limitations on viewable directions.  <P>SOLUTION: First optical pulses 12a to 12d are made incident on one of fluorescent spaces 11 at a prescribed repetitive cycle (interval L<SB>0</SB>). Second optical pulses 13a to 13d, into which cross-sectional information is written, are made incident on the other fluorescent space 11 at prescribed repetitive cycle (interval L<SB>0</SB>+ΔL) different from that of the first optical pulses. Consequently, at different positions within the fluorescent space 11, the first optical pulses 12a to 12d and the second optical pulses 12a to 12d overlap each other. Multi-photon absorption arises only at a location where the first optical pulse 12 and the second optical pulse 13 overlap each other, and thus induces fluorescence, thereby a three-dimensional video 14 is displayed which is comprised of these cross-sectional images 14a to 14d.  <P>COPYRIGHT: (C)2007,JPO&INPIT
