1,001 CAMERAS SEE IN GIGAPIXELS
As manufacturers of consumer digital cameras compete in increments, adding one or two megapixels to their latest models, David Brady of Duke University is thinking much bigger. Working with the U.S. Department of Defense's Defense Advanced Research Projects Agency, he is designing and building a camera that could achieve resolutions 1,000 or even 1 million times greater than the technology on the market today.
The goal of reaching giga- or terapixels, says Brady, is currently being held back by the difficulty of designing a spherical lens that will not distort small areas of a scene. His idea is not only to modify the shape of the camera lens -- making it aspherical -- but to link together thousands of microcameras behind the main lens. Each of these cameras would have its own lens optimized for a small portion of the field of view.
"Now, when you use a camera, you're looking through a narrow soda straw," says Brady. "These new cameras will be able to capture the full view of human vision."
The final result of the three-year project should be a device about the size of a breadbox, though Brady hopes to scale the technology down to create a single-lens reflex camera with a resolution of 50 gigapixels. (Paper CWB2, "Multiscale Optical Systems" is at 2 p.m. Wednesday, Oct. 14).
Here is the LINK to the page the article is on.
That's not a new idea and it's already been constructed and used is astro-photography. I'll look for the site and link it when/if I find it again. About 4 years ago I was contracted to create a presentation video for it. There was one extremely large aspherical lens (I dunno the number of elements) over the sensor array and each sensor (I think they were CMOS) had it's own custom lens - again aspherical and I assume a multi element construction. If I remember right there were 800 24MPx sensors: MF Digital back chips used by some famous make, I forget.
Anyway these two sound about the same to me.
