Help me Obi-Wan… – 3d images in the air…
Display technology has come a long way, but the 3d holographic display that is so recognizable in hollywood special effects in movies like Star Wars have just not been anything within the realm of possibility. I recall seeing one display that used fog to shine the light on, but that was two dimensional (although you might could do 3d…) Using lasers though Japanese researchers have created brilliant dots of light in the air that can be the components for an image. The technology is certainly early in development, but it reads as though they are cooking air into plasma with the lasers and the molecules give off light in the process. There’s a lot of popping and crackling and I suspect you could have severe discomfort if you accidentally tripped over the device…. Looks neat though.
