Abstract
SE PRESENTA UN APARATO PARA ENFOCAR UNA IMAGEN EN UN RECEPTOR DE IMAGENES (20). EL APARATO INCLUYE UNA LENTE FIJA (10), UN CUADRO ROTATIVO (40) CONECTADO DE MANERA RIGIDA AL RECEPTOR DE IMAGENES (20) Y UNA BASE. LA BASE SE ENCUENTRA CONECTADA DE MANERA PIVOTANTE AL MARCO ROTATIVO (40) ALREDEDOR DE UN EJE DE ROTACION. LA LENTE FIJA (10) ENFOCA LA IMAGEN SOBRE EL RECEPTOR DE IMAGENES (20) A BASE DE HACER PIVOTAR AL MARCO ROTATIVO (40) ALREDEDOR DEL EJE DE ROTACION. EN UN ASPECTO ALTERNATIVO DE LA INVENCION, UN APARATO PARA ENFOCAR UNA IMAGEN SOBRE UN RECEPTOR DE IMAGENES (20) INCLUYE UNA LENTE FIJA (10), UN ACCIONADOR DE BOBINA MOVIL (100), UN SERVOBUCLE PARA ACCIONAR AL ACCIONADOR DE BOBINA MOVIL Y UN TRANSDUCTOR ELECTROMECANICO (80) PARA DETERMINAR LA POSICION DEL RECEPTOR DE IMAGENES (20). EL TRANSDUCTOR ELECTROMECANICO (80) SE ENCUENTRA CONECTADO ELECTRICAMENTE AL SERVOBUCLE. TAMBIEN SE PRESENTAN LOS ELEMENTOS DE CONEXION UTILIZADOS PARA CONECTAR DE MANERA RIGIDA EL RECEPTOR DE IMAGENES (20) AL ACCIONADOR DE BOBINA MOVIL (100). LA LENTE FIJA ENFOCA LA IMAGEN SOBRE EL RECEPTOR DE IMAGENES (20) A BASE DE EXCITAR AL ACCIONADOR DE BOBINA MOVIL. SE PRESENTA UN METODO PARA ENFOCAR UNA IMAGEN SOBRE UN RECEPTOR DE IMAGENES CONECTADO DE MANERA PIVOTANTE A UNA BASE ALREDEDOR DE UN EJE DE ROTACION. EL METODO CONSISTE EN DETECTAR LA INFORMACION REPRESENTATIVA DE LA DISTANCIA ENTRE UNA LENTE FIJA Y UN OBJETO DEL QUE SE ESTA FORMANDO UNA IMAGEN Y EN HACER PIVOTAR AL RECEPTOR DE IMAGENES ALREDEDOR DEL EJE DE ROTACION SEGUN LA INFORMACION DETECTADA.
