Title (EN) POSITIONAL ALIGNMENT MECHANISM FOR A LENS ASSEMBLY
(FR) MÉCANISME D'ALIGNEMENT DE POSITION POUR ENSEMBLE LENTILLE
Abstract:
(EN) An alignment mechanism to position and focus a lens assembly includes a housing and an eccentric shaft supported by the housing. The eccentric shaft is configured to rotate with respect to the housing. The alignment mechanism further includes a lens assembly having a bracket coupled to the eccentric shaft, and an actuator assembly, coupled to the bracket of the lens assembly and configured to rotate the lens assembly about the eccentric shaft. The alignment mechanism further includes at least one thrust drive nut mounted on the eccentric shaft, the at least one thrust drive nut being configured to move the eccentric shaft and the bracket of the lens assembly in a z-axis direction.
(FR) Mécanisme d'alignement pour positionner et concentrer un ensemble lentille comprenant un boîtier et un arbre excentrique supporté par le boîtier. L'arbre excentrique est conçu pour tourner par rapport au boîtier. Le mécanisme d'alignement comprend en outre un ensemble lentille ayant un support accouplé à l'arbre excentrique, et un ensemble actionneur, accouplé au support de l'ensemble lentille et conçu pour faire tourner l'ensemble lentille autour de l'arbre excentrique. Le mécanisme d'alignement comprend en outre au moins un écrou d'entraînement de poussée monté sur l'arbre excentrique, le ou les écrous d'entraînement de poussée étant conçus pour déplacer l'arbre excentrique et le support de l'ensemble lentille dans une direction d'axe z.
