which displays natural 3D images without requiring special glasses. In fact, we are engaged in R&D on new devices that display holographic 3D images. The basic principles of holography are ...

They say that they were able to create realistic 3D holographic displays ... and the new approach shows that we can create holographic displays on a much more affordable level than the expensive ...
