Title
(EN) DISTURBANCE REJECTION FOR LASER BEAM SCANNING DISPLAY
(FR) REJET DE PERTURBATION POUR DISPOSITIF D'AFFICHAGE À BALAYAGE LASER
Abstract
(EN) A laser beam scanning ("LBS") display device comprises a laser beam emitter (302) configured to emit a laser beam. The LBS also includes a driver configured to generate a driving signal for controlling a microelectromechanical systems ("MEMS") mirror. The LBS also includes a controller (380) configured to generate a driving signal (320B) while rejecting a system disturbance response (D1(s)).
(FR) Un dispositif d'affichage à balayage laser («LBS ») comprend un émetteur de faisceau laser (302) conçu pour émettre un faisceau laser. Le LBS comprend également un pilote conçu pour générer un signal de commande pour commander un miroir de systèmes micro-électromécaniques (« MEMS »). Le LBS comprend également un contrôleur (380) configuré pour générer un signal de commande (320B) tout en rejetant une réponse de perturbation du système (D1(s)).
