Nokia Lumia 1020 captures image of objects obstructed from view
The world of photography is incredible. It's a feat to capture the world and view any scene at a later date in glorious high definition, but it's another to further develop the technology to produce some extraordinary results.
We are now learning that physicists have managed to use the Nokia Lumia 1020 to capture a photo and reveal objects hidden behind a piece of frosted glass.
Using single-pixel imaging, an image taken from behind frosted glass captures an entirely random pattern of light, but should a sequence of images taken this way be reconstructed, it is possible to crunch the data from numerous images and produce an image of the concealed object. Usually this would include a rather powerful computer to handle the image processing.
Ori Katz and a handful of colleagues at the Institut Langevin in Paris have managed to achieve similar results using nothing more than a smartphone – the Lumia 1020. The team treats data from each pixel as an individual image and look for the correlation between all the images. There's no need for a lens as the light doesn't require to be refocused.

Smartphones in general cause issues for this type of image processing as lenses are unnecessary (requiring a pinhole aperture) and each device produces compressed jpeg images, but luckily these files can still be used. The end results are reportedly impressive, with images reconstructed to reveal objects behind onion skin and even chicken breast tissue.
It's fairly revolutionary technology with many possible applications that include space exploration with orbiting observatories and medical imaging. Imagine the frosted glass being soft tissue and having the ability to photograph an object just beneath the tissue without the need for x-rays or exploratory surgery.
The added bonus is that a Windows Phone was utilized in the development, which will allow scientists to scale down imaging equipment and be more cost efficient.
