A
major advanced technological foster in the field of high speed beam-scanning
devices can increase the speed of 2D and 3D printing by up to 1,000 times, the researchers
have been reported. By Using a space-charge-controlled KTN beam (an object that
pushes aside the flow of something) a kind of crystal made of potassium tantalite
and potassium niobate with a large electro-optic effect, the researchers found
that the scanning at a much higher speed is possible. This research was
published in the journal Scientific Reports, could benefit everyone, in that
something being printed in 3D that once took an hour would now take seconds,
and 20,000 pages printed in 2D would take one minute, said Shizhuo Yin,
Professor at School of Electrical Engineering and Computer Science,
Pennsylvania State University, US. Basically, when the crystal materials are
applied to an electric field, they create uniform reflecting distributions,
that can push aside an incoming light beam, Yin said. We managed
and did/done a well-thought-out study on indications of speed and found out the
phase change (from one thing to another) of the electric field is one of the
limiting factors," Yin noted. To overcome this issue, Yin and his team of
(people who work to find information), eliminated the electric field-caused
phase change (from one thing to another) in a nanodisordered KTN crystal by
making it work at a higher temperature. They not only went beyond the Curie
temperature (the temperature in which certain materials lose their magnetic
properties, replaced by caused magnetism), they went beyond the critical end
point in which a liquid and its vapour can live together.
This
increased the scanning speed from the microsecond range to the nanosecond
government in power and improved high-speed imaging, broadband optical
communications, and ultra-fast laser display and printing, said the study. A
technology like this would be especially meaningful in the medical industry -- high
speed imaging would now be in (happening or viewable immediately, without any
delay), Yin said. For example, optometrists who use a non-harmful imaging test
that uses light waves to take (thin slice that can be looked at) pictures of a
person's retina, would be able to have the 3D image of their patients' retinas
as they are (doing/completing) the surgery, so they can see what needs to be
corrected during the procedure, the (people who work to find information)
explained.
