Technology Craze: Scientists
from the University of Rochester, New York USA is developing innovations in the
field of optical lenses. This
optical lens can make users seem to disappear. Similar to cloaking ability in the
Harry Potter films, but these innovations are developed utilizing an optical
lens.
There are many high-tech approach to cloaking and the basic idea
behind this technology, such as taking the light and let it pass around
something as if it does not exist, thus revealed John Howell, professor of
physics at the University of Rochester.
Howell
and graduate student Joseph Choi developed a combination of four standard lenses
that makes the hidden object. This
is the first device that we know of that can do three dimension, multi
directional cloaking continuously, said Choi.
In a
trial, they put objects in front a lens background grid or striped. As they look through the lens and
change the angle of view, the grid turned out to shift.
In a
paper to appear in the journal Optics Express, Howell and Choi uncover a type
of cloaking mathematical calculation for this type of work for angles up to 15
degrees or more. They used a
technique called the ABCD matrix.
The
matrix illustrates the bend, how to light when it passes through a lens,
mirror, or other optical elements. This
technology is expected to be applied to assist the surgeon, so that doctors
could see what he was doing behind his work when dissecting the patient, not
for other people to see her underwear visible.
