‘True 3D’ Display Using Laser Plasma Technology
Technology is getting closer to the current 3D Holy Grail - the ‘Princess Leia Hologram’:
This True 3D display technology, developed by Burton, uses a laser to creates luminous points of light at desired locations in air or underwater.
This system is an evolved version of technology co-developed by AIST and Keio University, first announced in 2006. It works by focusing laser light, to produce plasma excitation from the oxygen and nitrogen in the air. The researchers state that this is the world’s first technology to show pictures without the constraint of a screen.
“This system can create about 50,000 dots per second, and its frame rate is currently about 10-15 fps. But we’re working to improve the frame rate to 24-30 fps.”
In this demonstration, to make the system more compact, a green laser is shone into water from below. But if a laser source with higher output is used, images can be displayed in air. A color display can also be achieved by using a combination of red, green, and blue lasers.
We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.
