Abstract

REFLECTOR RECTANGULAR CAPAZ DE EVITAR LA REFLEXION SECUNDARIA PRODUCIDA POR LAS PAREDES LATERALES. UN REFLECTOR CONSTA DE UNA PORCION REFLECTORA Y UNA PORCION DE PARED RODEANDOLA Y ES RECTANGULAR SEGUN SE VE DESDE EL LADO FRONTAL. SE FORMA UNA CURVA DE REFERENCIA EN UN PLANO HORIZONTAL QUE INCLUYE EL EJE OPTICO CONECTANDO PORCIONES EXTERIORES DE UNA PARABOLA QUE TIENE UN FOCO F1 SITUADO EN EL EJE OPTICO Y UNA DISTANCIA FOCAL F1, Y PORCIONES DE DOS PARABOLAS QUE TIENEN FOCOS F2 Y F2" SITUADOS EN SUS EJES PARALELOS CON EL EJE OPTICO Y UNA DISTANCIA FOCAL F2 (> F1). SE FORMA UNA SUPERFICIE REFLECTORA COMO CONJUNTO DE CURVAS TRANSVERSALES OBTENIDO CADA UNA CORTANDO CON UN PLANO VERTICAL QUE INCLUYE EL EJE DE LA PARABOLOIDE DE REVOLUCION UNA PARABOLOIDE IMAGINARIA DE REVOLUCION ESTABLECIDA PARA CADA PUNTO EN LA CURVA DE REFERENCIA Y QUE TIENE UN EJE QUE SE EXTIENDE A LO LARGO DE UN RAYO REFLEJADO EN DICHO PUNTO DESPUES DE SER EMITIDO POR EL FOCO F1.
