Resumen:
Our research interest is focused on studying the interaction of light with biological entities in orderto get information about the system in a non-destructive way.These systems usually present two special features: high concentration of chromophores and highlight scattering. From a spectroscopic and photophysical point of view, these peculiarities introducesome complexity in their study. Because of this, the accurate modelling of the interaction is usuallynecessary to avoid artifacts and to comprehend the processes that take place.In this talk, I will present some of our contributions in this area. They range from the developmentof theoretical approaches to the implementation of applied methodologies.I will describe physical models used in the analysis of chlorophyll fluorescence in leaves andcanopy with application in remote sensing [1, 2], optical methodologies for food control [3- 4] andquantification of fluorescence in vivo for evaluation of its relevance as a biosignal [5-7].Acknowledgments The University of Buenos Aires, Agencia Nacional de Promoción Científica yTecnológica and CONICET are acknowledged for financial support.References[1] Cordon, G.
