Abstract

Un dispositif de génération d'un ensemble de coefficients de corrélation spectrale d'un signal d'entrée inclut : un laser maître configuré pour générer un signal de peigne de fréquences optiques ; un premier modulateur optique configuré pour moduler le signal de peigne de fréquences optiques avec un signal d'entrée pour générer une pluralité de copies spectrales du signal d'entrée ; un élément dispersif configuré pour retarder la pluralité de copies spectrales du signal d'entrée d'un retard dépendant de la longueur d'onde ; un deuxième modulateur optique configuré pour moduler la pluralité retardée de copies spectrales avec un conjugué du signal d'entrée ; et un filtre en peigne optique configuré pour intégrer la pluralité modulée par conjugué de copies spectrales du signal d'entrée pour générer un ensemble de coefficients d'autocorrélation cyclique.
