Abstract

FACILITA LA DETECCION DE SUSTANCIAS QUIMICAS Y EMISORES DE RADIACION CON UNOS COSTES MUY INFERIORES A LOS DE LOS SISTEMAS CONOCIDOS Y CON UNA PRECISION SUFICIENTE PARA MUCHAS APLICACIONES TALES COMO LA DETECCION DE GASES EN MEZCLAS. EL PROCEDIMIENTO CONSISTE EN GENERAR UNA RADIACION QUE SEA PLANA EN UNA BANDA CARACTERISTICA DE LA SUSTANCIA O FUENTE A DETECTAR Y QUE ATRAVIESA UN AMBIENTE EN EL QUE SE ENCUENTRA DICHA SUSTANCIA, EFECTUANDOSE DESPUES UNA MODULACION DE LA RADIACION Y UNA DETECCION DE LA RADIACION MODULADA QUE APORTARA UNA SEÑAL DIRECTAMENTE RELACIONADA CON LA CONCENTRACION DE DICHA SUSTANCIA EN EL REFERIDO AMBIENTE. EL DISPOSITIVO CORRESPONDIENTE INCLUYE UNA LAMPARA (1) A LA QUE SE AJUSTA UNA GUIA OPTICA (2), DE MANERA QUE SE ILUMINE O RADIE EL AMBIENTE BAJO ESTUDIO; DISPONIENDOSE ENFRENTADAMENTE A DICHA GUIA (2) UN DETECTOR (4), E INTERCALANDOSE ENTRE AMBOS UN MODULADOR (3).
