@conference{10902/2346, year = {2004}, month = {6}, url = {http://hdl.handle.net/10902/2346}, abstract = {A device for the measure of index of refraction of liquids in situ based on polymer optical fibers (POFs) was demonstrated. It consists in a sensor head of three passive POFs where two are coupled to two detectors and an electronic unit for the differential measure of signals. A differential operating principle is utilized to reduce noise such as light intensity fluctuation. The device was successfully checked measuring refraction index changes of the water with different concentrations of sugar, salt and alcohol.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2004, vol. 5502, 325-328}, publisher = {Second European Workshop on Optical Fibre Sensors, Santander, 2004}, title = {In situ refraction index of liquid measurement using polymer optical fibers}, author = {Lomer Barboza, Mauro Matías and Zubia Zaballa, Joseba Andoni and Conde Portilla, Olga María and Mirapeix Serrano, Jesús María and Cubillas de Cos, Ana María and López Higuera, José Miguel}, }
