Abstract
UN METODO DE REALIZAR LA RESOLUCION DE IMAGEN EN UNA INSTALACION DE FORMACION DE IMAGENES. LA RESOLUCION OPTICA DE UN OBJETO SE REALZA REDUCIENDO PRIMERO EFICAZMENTE EL ANGULO DE EXPLORACION FORMADO ENTRE MUESTRAS ADYACENTES, HASTA LLEVARLO APRECIABLEMENTE POR BAJO DEL CORRESPONDIENTE AL LIMITE DE RAYLEIGH, A FIN DE OBTENER UNA IMAGEN BORROSA O CONFUNDIDA POR LA FUNCION DE DISPERSION DE PUNTOS (O MODELO DE DIFRACCION) DE LA ABERTURA. LA ETAPA SIGUIENTE CONSISTE EN TRATAR ESTA IMAGEN BORROSA PARA ELIMINAR LA BORROSIDAD. EL PROCEDIMIENTO DE ACLARAR LA IMAGEN CONSISTE EN PONER EN CONVOLUCION ESTA IMAGEN FINALMENTE MUESTREADA CON UNA MASCARILLA DE CONVOLUCION ESPECIALMENTE DISEÑADA. ESTA MASCARILLA TIENE POR EFECTO DAR SALIDA A UN ELEMENTO DE IMAGEN REALZADO, EN CADA ETAPA DE LA CONVOLUCION.
