Le projet P2P-FSO<\/a> vient de franchir une \u00e9tape d\u00e9terminante avec la r\u00e9ception de la nouvelle carte capteur ISB-SNAKE<\/strong>, con\u00e7ue par les \u00e9quipes de NEXVISION. Cette carte int\u00e8gre le capteur SWIR LYNRED SNAKE<\/strong> (640\u00d7512 \u2013 15 \u00b5m \u2013 InGaAs) et constitue un \u00e9l\u00e9ment cl\u00e9 du module de communication optique du projet.<\/p>\n\n

Pens\u00e9 pour les environnements militaires exigeants, P2P-FSO vise \u00e0 d\u00e9velopper un module de communication optique en espace libre, \u00e0 tr\u00e8s haut d\u00e9bit<\/strong>, capable d\u2019assurer des liaisons plateforme \u00e0 plateforme (ex : v\u00e9hicule \u00e0 v\u00e9hicule, v\u00e9hicule \u00e0 drone…) sur des distances allant de quelques m\u00e8tres jusqu\u2019\u00e0 25 km (typiquement 3 km), y compris lorsque les plateformes sont en mouvement.<\/p>\n\n

Un d\u00e9fi technologique : maintenir l\u2019alignement optique<\/h2>\n\n

La principale difficult\u00e9 des communications optiques en espace libre r\u00e9side dans l\u2019alignement pr\u00e9cis et continu des syst\u00e8mes optiques \u00e9metteurs et r\u00e9cepteurs. Ce d\u00e9fi est amplifi\u00e9 lorsque les plateformes subissent des vibrations, des d\u00e9placements ou des variations d\u2019orientation.<\/p>\n\n

Pour y r\u00e9pondre, le projet repose sur une architecture d\u2019alignement innovante en trois \u00e9tapes<\/strong> : un premier alignement grossier par radio, un pr\u00e9-alignement optique bas\u00e9 sur le SWIR gr\u00e2ce \u00e0 la cha\u00eene \u00e9mission\/r\u00e9ception ISB-SNAKE, puis un alignement fin garantissant des performances \u00e9lev\u00e9es et une stabilit\u00e9 du lien en conditions dynamiques.<\/p>\n\n

ISB-SNAKE : une brique technologique essentielle<\/h2>\n\n

La r\u00e9ception de la carte ISB-SNAKE marque une avanc\u00e9e d\u00e9cisive. Elle permettra de valider la seconde phase d\u2019alignement<\/strong>, indispensable \u00e0 la robustesse du lien optique en environnement r\u00e9el.<\/p>\n\n

D\u00e9velopp\u00e9 dans le cadre d\u2019un partenariat europ\u00e9en r\u00e9unissant ASENSE<\/a>,\u00a0HELLENIC INSTRUMENTS<\/a>,\u00a0Lambda-X<\/a>\u00a0and\u00a0Amphinicy Technologies<\/a>,\u00a0le projet P2P-FSO constitue une \u00e9tape majeure vers les syst\u00e8mes de communication optique militaires de nouvelle g\u00e9n\u00e9ration.<\/p>\n\n
