Abstract

UN SISTEMA OPTICO PARA LA PRODUCCION DE UNA FUENTE DE LUZ DE ALTA POTENCIA QUE COMPRENDE UN NUMERO DE DIODOS LASER, O FUENTES SIMILARES, QUE EMITEN LUZ EN UNA BANDA DE EMISION (8) TENIENDO UNA DIMENSION LARGA (EJE X) Y UNA DIMENSION CORTA (EJE Y) Y QUE TIENE UNA MAYOR APERTURA NUMERICA EN EL EJE Y QUE EN EL EJE X. LOS RAYOS LASER (11) SON ANAMORFICAMENTE EXPANDIDOS/REDUCIDOS POR MEDIOS DE FORMADO DE RAYOS (12) DE MANERA QUE LA ANCHURA DE CADA RAYO (11) EN EL EJE X SE INCREMENTA EN RELACION CON LA ANCHURA EN EL EJE Y. LAS IMAGENES (21) PRODUCIDAS EN EL FINAL DE LA FIBRA SON ASI ANAMORFICAMENTE MAGNIFICADAS DE MANERA QUE LA RELACION ANAMORFICA ENTRE LA MAGNIFICACION DE LA BANDA (8) EN EL EJE Y EN EL EJE X ES MAYOR QUE UNO. POR EL TEOREMA DE BRILLANTEZ, ESTA MAGNIFICACION ANAMORFICA DA COMO RESULTADO UNA CORRESPONDIENTE DISMINUCION RELATIVA EN LA APERTURA NUMERICA DEL EJE Y PARA PERMITIR UN CORRESPONDIENTE INCREMENTO EN EL NUMERO DE RAYOS (11), QUE PUEDEN AJUSTARSE DENTRO DEL ANGULO SOLIDO DELOBJETO
