The three-lobed viewfinder offers extreme depth-of-field – focusing on near and far objects in a single image

A new triple-lobe-like viewfinder has been developed that offers a feature that has yet to be integrated into mainstream camera devices, such as DSLRs and camcorders developed by Sony, Nikon, and other manufacturers.

Visitors examine the HDC-SDT750 camcorder with 3D technology at Panasonic’s booth at the IFA 2010 technology fair and consumer electronics trade fair at Messe Berlin on September 3, 2010 in Berlin, Germany. IFA 2010 will be open to the public from 3 to 8 September.

The participating scientists observed the unique bifocal compound eye system of trilobites, the prehistoric marine arthropods. They discovered that this extinct animal had eyes that are highly sensitive to light field information.

Thanks to this unusual ability, trilobites can focus on both near and far objects, which allows them to more efficiently avoid predators.

Now, a new study has explained how the new lens copies the ability of trilobite eyes.

According to a recent ScienceNews report, the new study titled “Trilobite-inspired Nanoscale Light Field Camera with Maximum Depth of Field” revealed a new camera lens that can focus on both near and far objects.

The great thing about this new lens is that it can deliver an extreme depth of field effect in a single image. However, there is one problem. The middle distance can be quite blurry.

Ivo Erk, a researcher in computational imaging at the University of Siegen, explained that capturing more depth information can provide better image output, allowing experts to see more details.

Triple-lobed body for the camera lens

The camera experts involved were able to create a trilobite-like lens by fabricating an array of tiny lenses, forming what are called metallic lenses.

Because of this, more light can enter the viewfinder. On the other hand, flat glass was created to house tiny lenses (nanopillars).

These nanotubes are positioned at different heights so that light can pass through them at different levels. The short nanobeams are used for capturing near targets, and the long ones are for distant ones.

Meanwhile, a new MIT camera lens was recently revealed that can focus light faster and more efficiently.

On the other hand, very thin metals may replace bulky lenses in cameras, phones, and telescopes.
