Abstract

SE COLOCA UNA FUENTE DE RADIACION ELECTROMAGNETICA, TAL COMO UNA LAMPARA DE ARCO, EN UN PUNTO DESPLAZADO RESPECTO AL EJE OPTICO DE UNA SUPERFICIE REFLECTORA CONCAVA TOROIDAL. EL REFLECTOR CONCAVO PRIMARIO ENFOCA LA RADIACION PROCEDENTE DE LA FUENTE A UN PUNTO DE IMAGEN DESPLAZADO DEL EJE QUE SE ENCUENTRA DESPLAZADO DEL EJE OPTICO. EL USO DE UNA SUPERFICIE REFLECTORA CONCAVA AUMENTA LA EFICACIA DE CAPTACION DE UN OBJETIVO PEQUEÑO, TAL COMO UNA FIBRA OPTICA, RESPECTO A UNA SUPERFICIE REFLECTORA ESFERICA YA QUE REDUCE SUSTANCIALMENTE LAS ABERRACIONES PROVOCADAS POR LA GEOMETRIA DESPLAZADA DEL EJE. SE COLOCA UN SEGUNDO REFLECTOR CONCAVO ENFRENTE DEL PRIMER REFLECTOR PARA AUMENTAR AUN MAS EL FLUJO TOTAL CAPTADO POR EL OBJETIVO PEQUEÑO.
