Wikipedia导读:三维成象
http://en.wikipedia.org/wiki/Volumetric_display
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.
换句话就是说,他们在空气里造出了三维影像!
