Elastic Electronics See Better

Posted August 07, 2008 8:23 AM

From BBC News | Technology | World Edition:

A new camera designed with a curved detection surface allows imaging devices to see as animals do. The camera, inspired by the human eye, relies on the ability to construct silicon electronics on a stretchable membrane. In the future, these electronic membranes could be wrapped around human organs to act as health monitoring devices, say US-based developers. The new technology is described in a paper in the journal Nature. Photosensitive displays - like the ones used in digital cameras - are made up of thousands of pixels and are usually formed on a flat, rigid, semiconductor wafer, explained Dr John Rogers from the University of Illinois at Urbana-Champaign, US, who led the team of researchers. "No animal's eyes are like that; the retina is curved," Dr Rogers said. "This curvature allows animals to see the world without distortion - unlike the images produced from cameras, which lose focus at the periphery."

What a load of bollocks...
The 'in focus' portion of vision is pretty small and central...peripheral vision tends to detect movement..
The macular is the most sensitive part of the retina...
(I reserve the right to be wrong, as I'm thinking human vision here....)

This statement is true. The same could be said about visual optics (eyeglasses). Most people with 'mild' eye conditions won't notice it, but the higher your Rx goes (like your's trully) peripheral vision out of the lens becomes distorted (read up on abb (aberation) value and it's consequences on vision). Cameras are a series of lenses trying to put the whole optical area 'in focus' on a flat surface. Again...when looking at normal range shot (analogue or digital), all looks OK...but when you do macro shots, this distortion becomes evident.


Just my take

I can see many useful applications of this new development.

As far as "seeing the same as an animal" - the animal needs to be specified, because goldfish see differently from eagles, and eagles see differently from bees, which see differently from spiders....the differences are markedly clear, all we need to do is look, and we can see the differences.

Kind Regards....

I think I see what you mean... I mean, I see what you think... (You see what I think I mean?)
