Abstract
UN DETECTOR QUIMICAMENTE SENSIBLE (10) CAPAZ DE DETECTAR CAMBIOS EN CONCENTRACIONES DE IONES, ATOMOS O MOLECULAS EN UN MEDIOAMBIENTE FLUIDO (38) EN EL QUE EL DETECTOR ESTA SUMERGIDO O EMPOTRADO COMPRENDE UNA FIBRA OPTICA CHAPADA FINA (26), LA CUAL ESTA REVESTIDA CON UN POLIMERO (34) QUE ES PERMEABLE A LO LIQUIDO Y QUE CONTIENE UN MATERIAL QUIMICAMENTE SENSIBLE, Y UNA FIBRA PORTADORA DE LUZ (20). EL MATERIAL POLIMERICO TIENE LA CAPACIDAD DE CAMBIAR DE COLOR Y/O LA ABSORCION CUANDO LA CONCENTRACION DEL ION, ATOMO O MOLECULA EN EL MEDIOAMBIENTE CIRCUNDANTE CAMBIA. EL POLIMERO VOLVERA A SU ESTADO DE COLOR Y/O DE ABSORCION ORIGINAL UNA VEZ QUE LA CONCENTRACION VUELVA AL VALOR ORIGINAL. EL CAMBIO DE COLOR O ABSORCION SE DETECTA A TRAVES DEL NUCLEO (30) DE LA FIBRA OPTICA QUE SE CONECTA A UN FOTODETECTOR (28). EL ACOPLAMIENTO DE LA LUZ (22) DENTRO DE LA ESTRUCTURA DE DETECCION SE OBTIENE USANDO UNA FIBRA OPTICA DE UN SOLO NUCLEO (20) RODEADA POR UN MATERIAL CHAPEADO (36), ADEMAS DE UNA FUENTE DE LUZ EXTERNA (24). EL ACOPLAMIENTO DEL HAZ DE LUZ EXTERNO CON LA FIBRA REVESTIDA POLIMERICA SE OBTIENE A TRAVES DE PERDIDAS DE MICROALABEOS OPUESTOS ARROLLANDO LA FIBRA REVESTIDA ALREDEDOR DEL MATERIAL CHAPEADO. LOS CAMBIOS TALES COMO PH, CONCENTRACION METAL U OTROS CONCENTRACION DE MOLECULA ORGANICA, Y CONCENTRACION DE MOLECULA DE GAS PUEDEN SER DETECTADOS.
