Abstract

Un dispositivo para recibir un haz de radiación óptica primario (35) y para separar espacialmente los componentes de frecuencia del haz primario (35), el cual comprende: medios (31; 40) para separar el haz primario en una pluralidad de haces de radiación secundarios, teniendo cada haz de radiación secundario una fase respectiva, i, una pluralidad de guías de ondas (32; 41) polarizables eléctricamente y que forman una matriz o conjunto ordenado de guías de ondas, destinada cada una de ellas a transmitir un haz de radiación secundario a una salida, en la cual cada guía de ondas (32; 41) tiene una línea de retardo óptico asociada (33; 43) que presenta un tiempo de retardo óptico correspondiente, y en la cual cada uno de los tiempos de retardo ópticos es diferente, medios (42) destinados a aplicar un campo eléctrico variable a través de cada una de las guías de ondas (32; 41), de tal forma que la fase, i, de cada uno de los haces de radiación secundarios transmitidos a través de la respectiva guía de ondas (32; 41) puede ser modificada variando el campo eléctrico, estando las guías de ondas (32; 41) dispuestas de un modo tal, que los haces de radiación secundarios proporcionados en la salida de cada una de las guías de ondas (32; 41) interfieren con un haz de radiación secundario proporcionado en la salida de al menos una de las otras guías de ondas, a fin de formar un patrón de interferencia de campo lejano en una región de propagación, comprendiendo el patrón de interferencia de campo lejano uno o más máximos en diversas posiciones de la región de propagación, y de forma que el patrón de interferencia de campo lejano puede detectarse en al menos dos posiciones de la región de propagación, caracterizado porque el dispositivo comprende adicionalmente medios (36, 50) para aplicar una modulación de RF al haz de radiación óptica primario (35).
