Abstract
La présente invention concerne un dispositif d'acquisition ou de production de signaux optiques par modulation de supports optiques. Ledit dispositif comprend: des éléments de production d'au moins un rayonnement lumineux de référence qui, par rapport au signal optique à acquérir, est décalé en fréquence et/ou modulé en fréquence ou déphasé et/ou modulé en phase et/ou décalé dans le temps; des éléments permettant de corriger le signal optique à acquérir et/ou le(s) rayonnement(s) lumineux de sorte qu'ils peuvent être utilisé pour l'interférence; au moins un détecteur avec démodulateur, qui permet de détecter une modulation d'amplitude.
