Title (EN) OPTICAL BEAM STEERING AND SAMPLING APPARATUS AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ D'ORIENTATION ET D'ÉCHANTILLONNAGE D'UN FAISCEAU OPTIQUE
Abstract: front page image
(EN)In a light (optical) beam steering/sampling system, a matrix inversion control technique is used to decouple the operation of the actuators which drive the steering mirrors. The control technique uses two virtual variables, each having an associated independent feedback loop operating in a non-cross-coupled manner, each variable being associated with one of the two steering mirrors.
(FR)Dans un système d'orientation/échantillonnage d'un faisceau lumineux (optique), une technique de commande d'inversion de matrice est utilisée pour découpler le fonctionnement des actionneurs qui commandent les miroirs d'orientation. La technique de commande utilise deux variables virtuelles, chacune de celles-ci comportant une boucle de retour indépendante associée qui fonctionne sans couplage croisé, chaque variable étant associée à l'un des deux miroirs d'orientation.
