Abstract

UN LECTOR DE IMAGEN (10) PARA UN DISPOSITIVO DE PALPAR, MEDIANTE RAYOS LASER, UNA PLACA DE IMAGEN (12) EXPUESTA A RAYOS X, CON ELEMENTOS DE IMAGENES (40) QUE TIENEN UNA DISTANCIA (RADIO R) AL PUNTO CENTRAL DE LA PLACA DE IMAGEN; CON UN SOPORTE PARA LA PLACA DE IMAGEN (13), ACCIONADO POR UN MOTOR ELECTRICO (11) CON REVOLUCIONES AJUSTABLES Y SOBRE EL CUAL ESTA INSTALADA DE FORMA QUITABLE, LA PLACA DE IMAGEN (12); CON UNA UNIDAD DE PALPADO DE ELEMENTOS DE IMAGEN (15;115) QUE SE MUEVE POR LA PLACA DE IMAGEN (12) MEDIANTE UN ACCIONAMIENTO (14;18) CON UNA VELOCIDAD DE AVANCE QUE SE PUEDE DETERMINAR LIBREMENTE. IGUALMENTE TIENE UN DISPOSITIVO DE ALIMENTACION PARA LA LUZ DE LASER (42) Y UN DISPOSITIVO DE PALPADO OPTICO DE LOS ELEMENTOS DE IMAGEN (30A) DE UNA UNIDAD DE TRANSMISION DE VALORES DE MEDICION CON UN MULTIPLICADOR DE FOTOELECTRONES (36), ASI COMO UN DISPOSITIVO DE PREPARACION DE SEÑALES. ESTE LECTOR QUE QUIERE MEJORAR QUE AL PALPAR LA LUZ PARA TOMAR LA IMAGEN MEMORIZADA EN LA PLACA DE IMAGEN, SE OBTENGA EL MAYOR RENDIMIENTO DE LUZ POSIBLE. EL LECTOR DE IMAGENES DEBE SER COMPACTO Y POR ELLO SE PROPONE QUE LA UNIDAD DE PALPADO DE ELEMENTOS DE IMAGEN (15;115) PALPE CADA ELEMENTO (40) CON LA MISMA VELOCIDAD TANGENCIAL. PARA ELLO SE PREVE QUE LA ALIMENTACION DE LUZ DE LASER (42) TENGA UNA LENTE COLECTORA (44) CON UN FILTRO OPTICO (46), POTENCIADA POR DOS FUENTES DE LUZ DE LASER (43A, 43B), QUE ENFOCA LA LUZ DE LASER. EL EJE MOTRIZ (18) DEL MOTOR ELECTRICO (11) SE CONECTA CON UN HUSILLO MOTRIZ (26) MEDIANTE UN ENGRANAJE (23), ASI QUE SE PUEDE MOVER LA UNIDAD DE PALPADO DE ELEMENTOS DE IMAGEN (15) RADIALMENTE A LA PLACA DE IMAGEN (12).
