Title (EN) SYSTEM FOR TRANSMITTING DATA BY MEANS OF OPTICAL RADIATION AND METHOD ASSOCIATED THEREWITH
(FR) SYSTÈME DE TRANSMISSION DE DONNÉES AU MOYEN D'UN RAYONNEMENT OPTIQUE ET PROCÉDÉ ASSOCIÉ
Abstract:
(EN) A transmitter device (99) configured to transmit a signal through an optical radiation (108), said transmitter device (99) being characterized in that it comprises at least one modulator stage (101 ) having: - at least one photoemitter (100) configured to transmit the optical radiation (108); - an input (105) adapted to receive in use an electrical signal (s(t)) to be modulated, and - an output (107) transmitting, in use, towards the at least one photoemitter (100), one voltage or current driving signal (v7(t), i7(t)) for which said electrical signal (s(t)) represents a modulating signal, said driving signal (v7(t), i7(t)) being such that in use, the at least one photoemitter (100) transmits said optical radiation (108) with a radiation intensity (lr(t)) variable in accordance with said driving signal (v7(t), i7(t)), and wherein, between the input (105) and the output (107) there is at least one modulator stage (102; 103) configured for modulating, and/or modulating in use, according to at least one predefined modulation scheme comprising a frequency and/or phase modulation and an amplitude modulation.
(FR) L'invention concerne un dispositif émetteur (99) qui est configuré pour transmettre un signal à travers un rayonnement optique (108), ledit dispositif émetteur (99) étant caractérisé en ce qu'il comprend au moins un étage modulateur (101 ) comportant : - au moins un photoémetteur (100) configuré pour transmettre le rayonnement optique (108); - une entrée (105) apte à recevoir, lors de l'utilisation, un signal électrique (s(t)) à moduler, et - une sortie (107) transmettant, lors de l'utilisation, vers le ou les photoémetteurs (100), un signal de commande de tension ou de courant (v7(t), i7(t)) pour lequel ledit signal électrique (s(t)) représente un signal de modulation, ledit signal de commande (v7(t), i7 (t)) étant tel que, lors de l'utilisation, le ou les photoémetteurs (100) transmettent ledit rayonnement optique (108) à une variable d'intensité de rayonnement (lr(t)) selon ledit signal de commande (v7(t), i7 (t)), et, entre l'entrée (105) et la sortie (107), il existe au moins un étage modulateur (102; 103) configuré pour moduler et/ou moduler lors de l'utilisation, selon au moins un schéma de modulation prédéfini comprenant une modulation de fréquence et/ou de phase et une modulation d'amplitude.
