Bifocal Fibonacci Diffractive Lenses

Monsoriu Serra, Juan Antonio; Calatayud Calatayud, Arnau; Remón Martín, Laura; Furlan, Walter Daniel; Saavedra, G.; Andrés Bou, Pedro (Institute of Electrical and Electronics Engineers (IEEE): OAJ, 2013-06)

The focusing properties of diffractive lenses designed using the Fibonacci sequence are studied. It is demonstrated that these lenses present two equal intensity foci and that the ratio of the two focal distances approaches ...
Design of Binary-Sequence Zone Plates in High Wavelength Domains

Fuster Escuder, José Miguel; Pérez-López, Sergio; Candelas Valiente, Pilar; Rubio Michavila, Constanza (MDPI AG, 2018)

[EN] The design of zone plates is an important topic in many areas of physics, such as optics, X-rays, microwaves or ultrasonics. In this paper, a zone plate design method, which provides high flexibility in the shaping ...
Focusing properties of diffractive lenses constructed with the aperiodic m-bonacci sequence

Furlan, Walter D.; Ferrando Martín, Vicente; Monsoriu Serra, Juan Antonio (The International Society for Optical Engineering., 2014)

[EN] In this contribution we present a new family of diffractive lenses which are designed using the m-bonacci sequence. These lenses are a generalization of the Fibonacci Zone Plates previously reported. Diffractive ...
Fractal square zone plates

Calatayud Calatayud, Arnau; Ferrando Martín, Vicente; Gimenez Palomares, Fernando; Furlan, Walter Daniel; Saavedra, G.; Monsoriu Serra, Juan Antonio (Elsevier, 2013-01-01)

[EN] In this paper we present a novel family of zone plates with a fractal distribution of square zones. The focusing properties of these fractal diffractive lenses coined fractal square zone plates are analytically studied ...
Generation of programmable 3D optical vortex structures through devil s vortex-lens arrays

Calabuig, Alejandro; Sánchez Ruiz, Sergio; Martínez León, Lluis; Tajahuerce Romera, Enrique; Fernández Alonso, Mercedes; Furlan, Walter Daniel; Monsoriu Serra, Juan Antonio; Pons Martí, Amparo (Optical Society of America, 2013-08-10)

Different spatial distributions of optical vortices have been generated and characterized by implementing arrays of devil's vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the ...
Multiple-plane image formation by Walsh zone plates

Machado-Olivares, Federico Jose; Ferrando Martín, Vicente; Gimenez Palomares, Fernando; Furlan, Walter D.; Monsoriu Serra, Juan Antonio (The Optical Society, 2018)

[EN] A radial Walsh filter is a phase binary diffractive optical element characterized by a set of concentric rings that take the phase values 0 or ¿, corresponding to the values + 1 or ¿1 of a given radial Walsh function. ...
Quadrifocal diffractive lenses based on the aperiodic silver mean sequence

Garmendía-Martínez, Adrián; Furlan, Walter D.; Castro-Palacio, Juan Carlos; Monsoriu Serra, Juan Antonio; Ferrando, Vicente (Springer-Verlag, 2023-07)

[EN] In this work, we present a new quadrifocal diffractive lens designed using the silver mean sequence. The focusing properties of these aperiodic diffractive lenses coined silver mean zone plates are analytically examined. ...
