Abstract

AL TRATAR LA SUPERFICIE DE UN MATERIAL (22) CON ENERGIA LASER MEDIANTE BARRIDO DE UN RAYO LASER (12) SOBRE LA SUPERFICIE, UNA UNIFORMIDAD SUSTANCIAL (30) DE DISTRIBUCION ENERGETICA SE CONSIGUE A TRAVES DE UN FRAGMENTO IMPORTANTE DE LA ANCHURA TRANSVERSAL (X) DEL RAYO (12) UTILIZANDO UN RAYO NO ENFOCADO DE UNA CONFIGURACION EN MODO DE ANILLO Y PREFERENTEMENTE UNA QUE TIENE UN ANILLO EXTERNO (14) CON AL MENOS CIERTO GRADO DE RELLENO INTERIOR (16) COMO SE CONSIGUE MEDIANTE UN RAYO LASER QUE DESARROLLA LOS MODOS TEM00 Y TEM01. LA ESPECIFICACION ANALIZA DIVERSAS CONFIGURACIONES DE RAYOS. LA ESPECIFICACION INTRODUCE EL CONCEPTO DE "INTEGRACION DE EXPOSICION" QUE ES UNA FUNCION NO SOLAMENTE DEL PERFIL DEL RAYO EN LA DIRECCION DE BARRIDO (Z) SINO DE LA VELOCIDAD DE BARRIDO. UNA DURACION DE EXPOSICION PARA CUALQUIER PUNTO EXPLORADO (P) DE NO MAS DE 10 MILISEGUNDOS SE SUGIERE. LA APLICACION DEL INVENTO ES DESCRITA ESPECIALMENTE CON REFERENCIA A MARCAR LA SUPERFICIE DEL PAPEL.
