Fractal zone plates for wideband imaging with low chromatic aberration and extended depth of field
Walter D. Furlan, Genaro Saavedra, Juan A. Monsoriu
Fresnel zone plates are diffractive elements that are essential to form images in many scientific and technological areas, especially where refractive optics is not available. One…

Lacunar fractal photon sieves
Fernando Gimenez, Walter D. Furlan, Juan A. Monsoriu
We present a new family of diffractive lenses whose structure is based on the combination of two concepts: photon sieve and fractal zone plates with variable lacunarity. The focusi…
