9 p, 539.6 KB Terahertz time-domain spectroscopy of selected layered silicates / Janek, Marián (Comenius University. Department of Physical and Theoretical Chemistry) ; Bugár, Ignác (International Laser Centre) ; Lorenc, Dusan (TU Vienna. Institut für Photonik) ; Szöcs, Vojtech (Comenius University. Institute of Chemistry) ; Velic, Dusan (International Laser Centre) ; Chorvát, Dusan (International Laser Centre)
Micaceous layer silicate clay minerals are attractive materials for applications involving non-linear optics because of their low cost and ability to form well ordered, platy aggregates, but such applications require precise knowledge of the dielectric behavior of the clay. [...]

We present a novel approach for the optical manipulation of neutral atoms in annular light structures produced by the phenomenon of conical refraction occurring in biaxial optical crystals. For a beam focused to a plane behind the crystal, the focal plane exhibits two concentric bright rings enclosing a ring of null intensity called the Poggendorff ring. [...]

9 p, 1.4 MB Spherical subjective refraction with a novel 3D virtual reality based system / Pujol Ramo, Jaume (Davalor Research Center) ; Ondategui-Parra, Juan Carlos (Davalor Research Center) ; Badiella Busquets, Llorenç (Universitat Autònoma de Barcelona. Servei d'Estadística Aplicada) ; Otero, Carles (Davalor Research Center) ; Vilaseca, Meritxell (Davalor Research Center) ; Aldaba, Mikel (Davalor Research Center)
To conduct a clinical validation of a virtual reality-based experimental system that is able to assess the spherical subjective refraction simplifying the methodology of ocular refraction. For the agreement assessment, spherical refraction measurements were obtained from 104 eyes of 52 subjects using three different methods: subjectively with the experimental prototype (Subj. [...]

12 p, 98.7 KB Una propuesta de utilización de la historia de la ciencia en la enseñanza de un tema de física / Iparraguirre, Lorenzo Marcos
Este artículo describe el proceso para elaborar una propuesta orientada a mejorar la enseñanza de temas de óptica en nivel medio, basada en la creencia de que es necesario desarrollar una metodología esencialmente activa en la cual se introduzcan problematizaciones y cuestionamientos, y de que la historia puede brindar muchos elementos útiles para ello. [...]
This article describes the analysis of the possibilities to improve the teaching of optics subjects at middle school, based upon the belief in the need to develop an essentially active methodology which includes problematizations and questionings, and in the fact that history may provide very useful elements for this. [...]
