Abstract

L'invention concerne un système à laser pulsé conçu pour générer des impulsions optiques en réponse à la réception d'une commande provenant d'un ordinateur manipulé par un utilisateur. Le système à laser pulsé comprend une source de pompage conçue pour générer un signal de pompage; un microcontrôleur conçu pour recevoir une commande d'exécution en rafale provenant de l'ordinateur, générer un signal de modulation d'impulsion en fonction de la commande d'exécution en rafale et générer un signal de commande de pompage afin de commander la source de pompage lors de la génération du signal de pompage en fonction de la commande d'exécution en rafale; et un module de modulateur optique conçu pour générer des impulsions optiques en réponse au signal de pompage et au signal de modulation d'impulsions. Le microcontrôleur commande en temps réel les impulsions optiques en fonction de la commande d'exécution en rafale provenant d'un ordinateur manipulé par un utilisateur. Grâce à l'exécution de la commande en temps réel par le microcontrôleur, la sortie est efficacement séparée des erreurs, du bruit et des interférence qui peuvent s'introduire dans l'entrée de commande.
