Rituales, descentramientos territoriales y niveles de identidad: La Semana Santa Marinera de Valencia
2011
The aim of this paper is to study how the processes of spatial and identity recomposition brought about by a globalized world affect traditional religious rituals, with particular reference to the <i>Semana Santa Marinera</i> processions in Valencia (Spain). Instead of the ritual giving rise to a single local identity, it can be seen that levels of local identity —while not disappearing— overlap more and more with increasingly vague new territorialities ranging from processional networks based on canon law to state-organized meetings. Media coverage of the ritual means that new virtual communities with no fixed territorial base are created, and the complexity of this phenomenon …
Through-focus response of multifocal intraocular lenses evaluated with a spatial light modulator
2012
A new testing technique based on the use of a liquid crystal spatial light modulator (SLM) is proposed to analyze the optical quality of multifocal intraocular lenses (MIOLs). Different vergences and decentrations of the incident beam can be programmed onto the SLM in order to record the point spread function (PSF) for different object positions. From these axial PSFs, the through-focus modulation transfer function is computed. Because there are no moving parts in the experimental setup, this method is fast and versatile to assess MIOLs. Experimental results confirm the potential of the proposed method.
