Abstract

Se proporciona un modulador (10) de haz doble que incluye un cilindro (12) giratorio que tiene paredes (14, 15) anulares y un conjunto de una pluralidad de pasajes (18) de cuerda separados que se extienden a traves de las paredes entre orificios opuestos en la superficie exterior de las paredes (14, 15) cilindricas. Cada uno de los pasajes (18) estan separados radialmente alrededor de cada una de las dos paredes (14, 15) y longitudinalmente en la direccion del eje longitudinal del cilindro (12) para producir, en respuesta a un haz de radiacion incidente en forma de abanico (30) una serie de haces (28) electronicos estrechos separados conforme gira el cilindro (12). El cilindro (12) ademas tiene secciones (16, 17) de radio reducido sobre la superficie exterior de las paredes (14, 15) para hacer pasar periodicamente el haz (30) incidente en forma de abanico, alternativamente en la serie de haces (28) electronicos estrechos conforme gira el cilindro (12).
