Trilobite-style camera lens provides extreme depth-of-field capability, bringing both near and far objects into focus in a single shot

A new trilobite-type camera lens has been developed that provides functionality not yet incorporated into consumer cameras, such as DSLRs and video cameras developed by Sony, Nikon and other manufacturers .

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

The scientists involved observed the unique bifocal compound eye system of the trilobite, a prehistoric marine arthropod. They discovered that this extinct animal had eyes that were very sensitive to light field information.

With this unusual ability, a trilobite can focus on near and far objects, allowing it to more effectively avoid predators.

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

According to ScienceNews‘ latest report, the new study titled “Trilobite-inspired neural nanophotonic brightfield camera with extreme depth of fieldrevealed a new camera lens that can focus on both near and far subjects.

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

Ivo Ihrke, a computer imaging researcher at the University of Siegen, explained that capturing more depth information can provide better image output, allowing experts to see more detail.

Structure of trilobite type camera lens

The camera experts involved were able to create the trilobite-like lens by making an array of tiny lenses, forming the so-called metalens.

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

These nanopillars are placed at different heights so that light can pass through them at different levels. The short nanopillars are intended to capture close subjects and the long ones to distant objects.

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

On the other hand, ultra-thin metal lenses could soon replace bulky lenses in cameras, phones and telescopes.
