三维立体图像，不是戴上眼镜看的那种，而是像StarTreks里面的，一个立方盒子里显示的真实三维图像。我说的不是科幻，而是现实。现在市场上已经有了数几种商业化的产品，主要用于医学造影等用途。这篇文章介绍了世面上主要的几种技术，包括旋转成象、显示区块、全息成象等……

这篇文章(PDF)更加深入地介绍了各项技术的细节、软硬件架构、技术缺陷等，值得深入研究。

我觉得最酷的是日本人做的这个：

1. We have used laser produced plasma technology to make a flashpoint in the air.
2. We have greatly improved the brightness, contrast, and production distance of the plasma by optimizing the laser beams.
3. Using a laser plasma, we have been the first to succeed in displaying "real 3D images" in a space where there is nothing but air.
