[SD] New Single-Pixel Photo Camera Developed

post #1 of 9

Researchers from the UJI (Universitat Jaume I) Optics Research Group (GROC) in Castelló, Spain, have developed a new tool for the field of scientific imaging. A sensor of just one pixel can record high-quality images and distribute them securely, that is, without allowing unauthorised people access to information.

In 2009, Willard S. Boyle and George E. Smith received the Nobel Prize in Physics for having succeeded in capturing images with a digital sensor. The key was a procedure that recorded the electrical signals generated via the photoelectric effect in a large number of image points, known as pixels, in a short period of time. The CCD sensor in a photo camera acts as the human-eye retinal mosaic. Since their invention, the use of the digital format for recording images has revolutionised various fields, photography amongst them, as it facilitates image processing and distribution.

The GROC researchers have successfully captured 2D object images (such as the UJI logo or the face of one of the maids of honour from the famous Las Meninas painting as reinterpreted by Picasso in 1957) using this amazing single-pixel camera. The key for the success lies in the use of a small 1-inch LCD screen, similar to that used in video projectors or those we have at home, but in miniature. Its properties or features can be modified using a computer in order to generate the necessary light beams.

Furthermore, the researchers from Castelló have demonstrated, for the first time and on a worldwide scale, the possibility of adapting the technique in such a way that it allows an image to be securely sent to a set of authorised users using a public distribution channel, such as the Internet. The information transmitted is a simple numerical sequence that allows the image to be retrieved, but only if one knows the hidden codes enabling the generation of the noise patterns with which the pubic access information has been created.

So will the military be using this? Probably.

...does this mean that we can't be sure those dead pixels on our computer screen are, in fact dead pixels anymore?

On a serious(ish) not, that's a small camera!

I knew it. I knew the government was recording us from the difference in current from our LCD monitors. They thought I wouldn't be able to tell with all the noise, but I can tell.

And think! They're talking about just one pixel, and yet we have lots. 1920x1080 = lots of government cameras.

True story.

Maybe I missed it but I don't recall them saying exactly how big the pixel was, just that it was a single pixel meaning they captured the light of the entire photo using 1 photo-cell receptor. It could be 1 square inch big for all we know if I understand correctly. They stated that the breakthrough was the special screen they used to create the light that was captured, not the size of the camera, as well as the fact that through the single pixel technology, you could securely encrypt the photo.
