Focusing properties of fractal zone plates: experimental implementation with a liquid-crystal display Davis, Jeffrey A. Ramirez, Laura Rodrigo Martín-Romo, José Augusto Alieva Krasheninnikova, Tatiana Calvo Padilla, María Luisa We 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 shape and size of the focus points on critical design parameters is discussed. Additional unpredicted features are also described. 2023-06-20T10:42:46Z 2023-06-20T10:42:46Z 2023-06-20T10:42:46Z 2004-06-15 journal article https://hdl.handle.net/20.500.14352/51055 0146-9592 10.1364/OL.29.001321 eng TIC2002-1846 open access Alan E.
