González Montes, Mario ; Martínez Antón, Juan Carlos ; Vázquez Moliní, Daniel ; Álvarez Fernández Balbuena, Antonio ; Bernabeu Martínez, Eusebio | Hindawi Publishing Corporation | 2014This work is aimed to design and evaluate different achromatic Fresnel lens solutions capable of operating as concentrators aimed at photovoltaic cells systems. Throughout this study, the theoretical parametric design of the achromatic lens will[...]texto impreso
Mayorga Pinilla, Santiago ; Vázquez Moliní, Daniel ; Álvarez Fernández-Balbuena, Antonio ; Hernández Raboso, Gabriel ; Herráez, Juan Antonio ; Azcutia, Marta ; García Botella, Ángel | Elsevier | 2016-01A method to evaluate the risk of using daylight in museums and cultural heritage exhibitions is presented along this study. Although daylight is an ecological and sustainable source of energy and sometimes also an intrinsic part of the artwork, [...]texto impreso
García Botella, Ángel ; Álvarez Fernández-Balbuena, Antonio ; Vázquez Moliní, Daniel | The Society of Photo-Optical Instrumentation Engineers (SPIE) | 2017-09-07Nonimaging optics is focused on the study of methods to design concentrators or illuminators systems. It can be included in the area of photometry and radiometry and it is governed by the laws of geometrical optics. The field vector method, whic[...]texto impreso
García Fernández, Berta ; Álvarez Fernández-Balbuena, Antonio ; Vázquez Moliní, Daniel | OSA Publishing ; Chinese Laser Press | 2016The aim of this work is to provide an analytical method based on experimental measurements in order to obtain the prismatic film deformation for different curvatures of Hollow Cylindrical Prismatic Light Guides (CPLG). To conform cylindrical gui[...]texto impreso
Álvarez Fernández-Balbuena, Antonio ; González Montes, Mario ; García Botella, Ángel ; Vázquez Moliní, Daniel | Spie-Soc Photo-Optical Instrumentation Engineers | 2015-02-09Automatic optimization algorithms have been recently introduced as nonimaging optics design techniques. Unlike optimization of imaging systems, nonsequential ray tracing simulations and complex noncentered systems design must be considered, addi[...]texto impreso
González Montes, Mario ; Vázquez Moliní, Daniel ; Álvarez Fernández Balbuena, Antonio ; Bernabeu Martínez, Eusebio | Society of Photo-optical Instrumentation Engineers | 2014-06-20New aeronautical ground lighting techniques are becoming increasingly important to ensure the safety and reduce the maintenance costs of the plane's tracks. Until recently, tracks had embedded lighting systems whose sources were based on incande[...]texto impreso
Zoido Chamorro, Jesús Manuel ; Vázquez Moliní, Daniel ; Álvarez Fernández-Balbuena, Antonio ; Bernabeu Martínez, Eusebio ; García Botella, Ángel ; Herráenz Ferreiro, Juan Antonio ; Egido Rodríguez, Marian, del | SPIE | 2009-08-22This work is intended to deal with the problems which arise when illuminanting Paleolithic cave paintings. We have carried out the spectral and colorimetric characterization of some paintings located in the Murcielagos (bats) cave (Zuheros, Córd[...]texto impreso
Vázquez Moliní, Daniel ; García Fernández, Berta ; Álvarez Fernández-Balbuena, Antonio ; Serrano Ruiz, Jorge ; Roberto Raitelli, Mario ; García Botella, Ángel | 2019-06-14El objetivo fundamental de este proyecto es implementar el uso y el manejo de herramientas tecnologías informáticas innovadoras, englobadas dentro de las Tecnologías de la Información y la Comunicación (TIC) y basadas en software libre, en exper[...]texto impreso
Kamal Abd El-Hady, Hala ; Alda, Javier ; Vázquez Moliní, Daniel ; Bernabeu Martínez, Eusebio | Gustav Fischer Verlag | 2004In this paper we analyze different alternatives in the design of optimized optical arrays having spatial integration feature in a plane arrangement. More specifically, we focus our attention in the evaluation of the number of useful individual u[...]texto impreso
García Fernández, Berta ; Álvarez Fernández-Balbuena, Antonio ; Vázquez Moliní, Daniel | SPIE | 2019-09-09Prismatic film offer advantages such as the possibility of transmit light effectively in lighting applications with the benefit of reducing energy consumption. This paper presents several developments based on their characteristics which allow d[...]texto impreso
García Botella, Ángel ; Vázquez Moliní, Daniel ; García Fernández, Berta ; Álvarez Fernández-Balbuena, Antonio | SPIE | 2019The electric lighting is responsible for 15% of the electricity consumption, the efficiency in this sector has a good progress in recent years, it can still improve more. Conventional energy sources are polluting and limited, so it is essential [...]texto impreso
Vázquez Moliní, Daniel ; Álvarez Fernández-Balbuena, Antonio ; Canabal Boutureira, Héctor ; Muro, Carmen ; Durmus, D ; Davis, w ; Benítez Iglesias, Antonio Jesús ; Mayorga Pinilla, Santiago | Elsevier | 2019-11The need to achieve energy efficiency standards in the lighting systems of buildings makes it necessary to optimize all aspects of them. Here, the development of a light projection system that achieves this goal by studying and modifying the spe[...]texto impreso
