Polish and Japanese Researchers working on Holograms

Polish and Japanese researchers are working on a small hologram system that does not need any lenses. According to an article at Kurzweil (Source), “The new holographic lensless zoom is not the first lensless zoom system to be developed, but Tomoyoshi Shimobaba, a professor in the graduate school of engineering at Chiba University in Japan, notes that his team’s system requires only a laser and an LCD panel.”

Basically a ton of complicated math later, you have a less expensive hologram project system that just requires a laser and an LCD panel. This would be a really neat use of technology and would be pretty nice addon to any smart-phone or tablet IF it works well.
