La tomografía óptica coherente sensible a la fase (PhS-OCT), también conocida como microscopía de fase (SDPM), es una técnica que se basa en la medición de la fase en la señal de interferencia obtenida por tomografía óptica ...

Las nanopartículas constituidas por un núcleo dieléctrico rodeado por una capa metálica forman una clase de nanoestructuras con notables propiedades ópticas. Sus resonancias de plasmones superficiales derivan del acoplamiento ...

Focus error systems based on the astigmatic principle relying on four quadrant photo detectors as the signal generation element have widely been used in many different applications. Nevertheless, its working principle ...

Monodisperse gold nanorods with different sizes were synthesized and adsorbed on chemically modified glass substrates. Influence of surfactant molar concentration on nanorod adsorption was studied and the optimum range was ...

A heterodyne detection system for optical coherence tomography signalsis presented and characterized. The system allows to expand the range of measurement and overcome the limitations of conventional systems which typically ...
