Abstract

LA PRESENTE INVENCION SE REFIERE A PROCEDIMIENTOS Y A UN APARATO PARA DETERMINAR UNA CARACTERISTICA DE UNA MUESTRA DE MATERIAL MEDIANTE LA INTERACCION DE UNA RADIACION ELECTROMAGNETICA CON LA MUESTRA. DICHO APARATO COMPRENDE UNA FUENTE DE RADIACION ELECTROMAGNETICA, UN CONJUNTO OPTICO, Y UN DETECTOR. DICHO CONJUNTO OPTICO ILUMINA EN SECUENCIA VARIOS ELEMENTOS VOLUMICOS EN LA MUESTRA, DE FORMA QUE LA DISTRIBUCION DE LA INTENSIDAD EN LA MUESTRA CAE DE UN MODO ASI MONOTONO A PARTIR DE UNA PRIMERA ZONA DE UN PRIMER CAMINO OPTICO Y RECOGE LA RADIACION ELECTROMAGNETICA QUE EMANA DE CADA UNO DE LOS ELEMENTOS VOLUMICOS. EL CONJUNTO OPTICO PERCIBE LA RADIACION MAGNETICA QUE EMANA DE CADA UNO DE LOS ELEMENTOS VOLUMICOS CON UNA DISTRIBUCION PERCIBIDA, QUE CAE DE UN MODO SENSIBLEMENTE MONOTONO A PARTIR DE UNA SEGUNDA REGION DE UN SEGUNDO CAMINO OPTICO. LA PRIMERA Y LA SEGUNDA REGIONES SE SOLAPAN, POR LO MENOS, PARCIALMENTE EN CADA UNO DE LOS ELEMENTOS VOLUMICOS. EL DETECTOR DETECTA LA RADIACION ELECTROMAGNETICA PERCIBIDA QUE EMANA DE CADA UNO DE LOS ELEMENTOS VOLUMICOS ILUMINADOS EN SECUENCIA, DE FORMA QUE SE PRODUCEN RESPUESTAS REPRESENTATIVAS DE LA CARACTERISTICA DE CADA UNO DE LOS ELEMENTOS VOLUMICOS.
