Abstract

Dispositif d'enregistrement optique de données sur un support sensible. Un modulateur commande une source émettant un pinceau lumineux dirigé vers le support d'enregistrement par l'intermédiaire d'un transformateur à fibres optiques. Un calculateur est adapté à transformer des données analogiques en signaux numériques et à commander le modulateur par l'intermediaire d'une mémoire-tampon. Application à l'enregistrement d'échos de sonar ou de données sismiques.
