Abstract

UN APARATO Y UN METODO PARA CONTROLAR LA MODULACION DE UN HAZ DE EXPOSICION DE UN APARATO DE FORMACION DE IMAGENES TIPO POLIGONO ROTATIVO QUE HACE USO DE UNAS MARCAS DE CONTROL (32) FORMADAS SOBRE UNA PORCION SUPERFICIAL ROTATIVA (33) DE UN MIEMBRO DE POLIGONO (20) O UN CONJUNTO DE UN POLIGONO CON MOTOR. UN LECTOR (30) LEE LAS MARCAS DE CONTROL DURANTE LA ROTACION DEL MIEMBRO DE POLIGONO Y LA INFORMACION LEIDA EN LAS MARCAS DE CONTROL SE UTILIZA PARA CONTROLAR (31) LA MODULACION DEL HAZ DE EXPOSICION DEL APARATO DE FORMACION DE IMAGENES PARA EXPONER LAS LINEAS DE EXPLORACION DE PIXELS SEPARADAS DE MANERA REGULAR, DIMENSIONADAS DE MANERA UNIFORME, ORIENTADAS CON PRECISION, GEOMETRICAMENTE RECTAS SOBRE UN MIEMBRO FOTOSENSIBLE. LAS MARCAS DE CONTROL PUEDEN INCLUIR INFORMACION DE SINCRONIZACION DE PIXELS, INFORMACION DE CORRECCION DE LA INTENSIDAD, INFORMACION DE CORRECCION DE ERRORES SOBRE LAS FACETAS INDIVIDUALES DEL MIEMBRO DE POLIGONO, E INFORMACION DE CONTROL DE LA VELOCIDAD DEL MOTOR.
