The French Swiss artist—whose practice focuses on the Arctic, the oceans and the history of the Earth—finds connections with ...

Configure Reverse Lookup Zone. Before creating a Reverse Lookup Zone, you need to check what kind of zone it is going to be. Even though we have already created a Primary Zone earlier, this doesn ...

The use of concentric rings on a flat lens isn't new — a precursor, called a Fresnel zone plate, tries to do the same trick but is unable to eradicate chromatic aberration.

For the first time, a flat telescope lens has been produced that represents colors accurately, offering a way to make less bulky lenses that could be sent into space cheaply. The first telescopes ...

One existing type, called a Fresnel zone plate (FZP), uses concentric ridges to focus light, rather than a thick, curved surface. While this method does create a lightweight and compact lens, ...

Implementing Fresnel zones-based stacking is a pursuit in various seismic imaging methods. However, the estimation of Fresnel zones remains a challenge in 3-D migration. Migrated dip-angle gathers ...

Fresnel zone plates are extensively used as magnifying and focusing optical devices, offering high resolution. They consist of circular gratings with a radially increasing line density.
