The Digital Camera

Friday May 1st Celebrates - The Digital Camera

On May 1st 2013, the first digital camera was created that could mimic an insect compounds eyes.

Researchers built an artificial composite eye by first making a flat array of lenses and then inflating it into a spherical shape.

Now that summer is on its way, there are more insects coming out. Insects have a wide field of view and are acutely sensitive to motion, as anyone who has tried chasing a housefly with a fly swatter would willing not understand this right away.

Insect eyes are made up of hundreds or even thousands of light-sensing structures called ommatidia. Each contains a lens and a cone that funnels light to a photosensitive organ.

The long, thin ommatidia are bunched together to form the hemispherical eye, with each ommatidium pointing in a slightly different direction. This structure gives bugs a wide field of view, with objects in the periphery just as clear as those in the center of the visual field, and high motion sensitivity. It also allows a large depth of field objects are in focus whether they’re nearby or at a distance.

The biggest challenge in mimicking the structure of an insect eye in a camera is that electronics are typically flat and rigid, says John Rogers, a materials scientist at the University of Illinois at Urbana-Champaign. “In biology, everything is curvy,” he says.

“The whole thing is stretchy and thin, and we blow it up like a balloon” so that it curves like a compound eye, says Rogers. The current prototype produces black-and-white images only, but Rogers says a color version could be made with the same design.

Today’s YouTube presentation is brought to you by, the Associated Press; Scientists at the University of Illinois developed a miniature lens that “sees” like a bee. The panoramic view mimics Mother Nature’s optical system for some insects.

The next generation of digital cameras could show us how bugs see the world.

The insect world provides extremely impressive examples of engineering in the vision, flight, power and sensing systems. I, personally, have been intrigued by the insect eye for as long as I can remember.

In lieu of today’s story as an artist the key to seeing what’s really there, as opposed to whatever everyone sees. Creatively speaking leads to a proper truth, which regards ones person’s personal perception.

The more gadgets that come out, as new technology is discovered, the eye sees only what the mind is prepared to comprehend, because personal observation, becomes a valuable tool, when one learns how to use it.

How that’s for snap shot of information, I hope you have a wonderful weekend!
