Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Davis, Jeffrey A. ; Ramirez, Laura | The International Society for Optical Engineering (SPIE) | 2004We study experimentally and by numerical simulation the Fresnel diffraction on the recently introduced fractal zone plates (ZPs) associated with Cantor sets'. The focusing properties of these ZPs and the evolution of the intensity patterns at th[...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Calvo Padilla, María Luisa ; Davis, Jeffrey A. | Taylor and Francis Ltd. | 2005-12-15The paper reports studies, both experimental and using numerical simulation, of the Fresnel diffraction by recently introduced fractal zone plates associated with triadic and quintic Cantor sets. The evolution of the intensity patterns at planes[...]texto impreso
Davis, Jeffrey A. ; Ramirez, Laura ; Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Calvo Padilla, María Luisa | Alan E. Willner, University of Southern California | 2004-06-15We report the first experimental results, to our knowledge, with fractal zone plates implemented in a liquid-crystal display. Our results largely agree with theory for the axial irradiance distribution of these lenses. The dependence of the shap[...]texto impreso
Davis, Jeffrey A. ; Sigarlaki, Sean Paul ; Craven, Julia M. ; Calvo Padilla, María Luisa | The Optical Society Of America | 2006-02-20We report on a Fourier series approach that predicts the focal points and intensities produced by fractal zone plate lenses. This approach allows us to separate the effects of the fractal order from those of the lens aperture. We implement these[...]
