Fresnelzon
Fresnelzon is a term that refers to a specific type of zone plate used in optics and wave physics. It is named after Augustin-Jean Fresnel, a French physicist known for his work on the wave theory of light. A Fresnel zone plate is an optical element that, like a lens, can focus or diffract light. However, it achieves this through a different mechanism.
Instead of continuously varying curvature as in a lens, a Fresnel zone plate consists of a series
Fresnel zone plates can be designed to act as either converging or diverging elements. They have found
