In space, loose clouds of gas generate spontaneous laser emissions all the time. Now, physicists are for the first time creating lasers from gas clouds here on Earth--lasers unlike any gas-based laser we've ever seen.
With existing camera technology, capturing 3-D images as the biological eye does is difficult and time consuming; basic stereoscopy requires two images to create a single 3-D frame, which means that to shoot 3-D video you need at least two cameras rolling on the same subject at the same time (even the high-tech gear behind Avatar required two different lenses). But engineers at Fondazione Bruno Kessler (FBK) in Italy have created a single camera that can capture the third dimension, using laser detection and creative use of CMOS technology.
And that's not all: The camera's sensor also records the smallest pixel currently in the field, a mere ten millionths of a meter (roughly one tenth the size of a human hair). Add it all up, and it's one pretty sweet piece of machinery, with the ability to capture not only the highest quality of detail in images, but to produce a depth of vision you can only get by adding the third dimension.
