Abstract
CON EL FIN DE ALCANZAR CON UN DISPOSITIVO PARA EL MODELADO O CORRECCION DE LENTES OPTICAS, EN ESPECIAL DE LA CORNEA DEL OJO, CON UN LASER DE IMPULSOS, CUYOS IMPULSOS DE RADIACION SE DIRIGEN POR MEDIO DE ELEMENTOS DE REPRODUCCION Y DIAFRAGMAS SOBRE SUPERFICIES DE LENTES A MODELAR DE TAL FORMA QUE LAS SUPERFICIES ANULARES CONCENTRICAS SOBRE LA SUPERFICIE DE LA LENTE SE CARGAN CON UN DIFERENTE NUMERO DE IMPULSOS DE RADIACION Y, POR TANTO, SE EROSIONAN CON DIFERENTE PROFUNDIDAD, UNA DOSIFICACION PRECISA DE LA CANTIDAD DE IMPULSOS DE RADIACION SOBRE LA TOTALIDAD DE LA SUPERFICIE A TRATAR Y GARANTIZAR UN ENLACE EXACTO DE LAS SUPERFICIES RADIADAS, SE PROPONE QUE EN LA LENTE ESTE ALOJADA UNA MASCARA GIRATORIA ALREDEDOR DE UN EJE SITUADO PERPENDICULAR A LA SUPERFICIE DE LA LENTE, SUJETA A LA LENTE, QUE EN DIRECCION RADIAL PRESENTE VARIAS ESCOTADURAS DISPUESTAS CONCENTRICAS ENTRE SI EN DIRECCION DE LA PERIFERIA, CUYAS LONGITUDES SEAN DIFERENTES EN DIRECCION DE LA PERIFERIA, QUE UN ACCIONAMIENTO GIRELA MASCARA PASO A PASO Y QUE ESTE PREVISTO UN CONTROL PARA EL ACCIONAMIENTO Y PARA EL LASER, QUE ENCIENDA EL LASER CADA VEZ DESPUES DE QUE LA MASCARA HAYA SIDO GIRADA OTRA VEZ DURANTE LA PARADA DE LA MASCARA.
