a brand new digital camera that looks as if a flat sheet of
paper is so skinny and bendy that it may be wrapped round ordinary items, such
as desks, vehicles, streetlights and even clothing, new studies indicates.
the new tool ought to help flip any surface into a digicam,
and the discovery may additionally result in card-size cameras that may flex
for you to growth their area of view, the scientists stated.
everyday cameras take photos from a unmarried point in
space, however this new tool instead seeks to seize pix using a flat grid of
miniature cameras — a piece like an insect's compound eye. [Top Picks: Best
Cameras of 2016]
"wouldn't it's thrilling to layout a digicam you can
wrap around ordinary objects to capture perspectives that would be hard to do
with one or more traditional cameras?" said Shree Nayar, a pc scientist at
Columbia college and senior writer of the examine."consider wrapping it
round a pole to get a 360-degree view of the world for safety functions,"
Nayar stated."Or, if you want your office table to be greater clever, have
a sheet for your table that might analyze what's sitting on it."
The ultraflexible digicam would not be restrained in its
perspectives the manner conventional cameras are, he brought.
"And, if you could paintings this into clothing, it
could assist folks who are visually impaired be greater privy to their
surroundings," Nayar informed live technology.
One feasible method for a digital camera that may be a
flexible sheet could involve inflexible lenses connected to a pliable sheet.
but, bending this sheet would bring about gaps among the fields of views of
adjacent lenses, the researchers said. this would cause the ensuing photo to
have missing information, they said.
instead, the researchers developed an elastic sheet made
from bendy lenses. no matter how this sheet is bent, there are no gaps between
the lenses, the scientists said.

Nayar and his colleagues evolved a flexible array that
includes nearly 1,100 lenses product of silicone rubber. by using optimizing
the geometrical proportions of the lenses and the fabric residences of the
sheet, the scientists located that this array ought to produce exquisite images
even if bent and twisted.
The researchers tested how well their flexible lens sheet
created snap shots by way of focusing the light from all of its lenses onto a
single normal camera. future research nevertheless wishes to plan a pliable
grid of light-detecting image sensors to accompany each of its lenses and
actually produce a digital camera, Nayar stated.
The researchers mentioned that, in precept, it's far
feasible to manufacture a lens array the scale of a credit score card made of
millions of lenses. one day, it also may be feasible to print both the lens and
the sensor arrays together, Nayar stated.
Nayar and his colleagues Daniel Sims and Yonghao Yue at
Columbia college will gift their paintings on may 14 at the global conference
on Computational photography at Northwestern college in Evanston, Illinois.
