Holography is amazing. Do you know much about so-called "free space optical" data transmission? I worked with some gear a few years ago that could transmit & receive using multiple lasers at 1Gbit. I was fascinated with that stuff, but the vendor had their folks do all the alignment and installation. So, I didn't get to work with it much. I wonder if you've seen faster speeds than that. I also wonder what the power levels look like for those lasers and what distances the really serious ones can reach. Can they still work in bad weather? It seemed like the ones that I mentioned, still worked in the rain. -Swift PS: It was the May 1984 National Geographic cover that blew me away and made me forever respect holography. :-)
