I'm not sure if this would be better put in the Engineering or Technology forum. I'm just wondering why the field of optics seems to be taking so long to make significant progress. Maybe I've just missed something, but when are we going to see 3-D holographic movies and television? And what about holographic memories that were supposed to have so much more capacity than conventional memories? I've seen lots of holographic art. And I've heard of a company a while ago (Holotronics?) that was producing a device for transmitting holograms electronically, but what's become of this? It seems like the next big breakthrough in display technology after HDTV would be 3DTV. Does anyone have any more information about this than I do? I would be interested in hearing about this.
Thanks.
