摘要： An objective lens actuator is provided with an objective lens holder and a tilting coil that drives the objective lens holder in a tilting direction. The tilting coil is inclined with respect to the horizontal direction, so that a rotation center when the objective lens holder is driven in the tilting direction, is located on extension lines of sides that effectively contribute to driving the objective lens holder in the tilting direction by interaction between a magnetic field formed by a magnet and current that is supplied and flows in the coil among sides of the tilting coil.

摘要： In a variable-shape mirror of which the shape of the mirror surface can be varied, a mirror portion is bonded only to a fixed portion and not to a piezoelectric element. When the piezoelectric element is not operating, the mirror portion, receiving a predetermined force from the piezoelectric element, makes contact with the piezoelectric element. When the piezoelectric element contracts, the mirror portion tends to restore its original shape by its counterforce. Thus, even when the piezoelectric element contracts, the contact between the mirror portion and the piezoelectric element is held, and hence the electric conduction to the piezoelectric element is maintained.
摘要翻译：在镜面的形状可以变化的可变形反射镜中，镜部仅与固定部分接合而不与压电元件接合。当压电元件不工作时，接收来自压电元件的预定力的反射镜部分与压电元件接触。当压电元件收缩时，反射镜部分倾向于通过其反作用力恢复其原始形状。因此，即使当压电元件收缩时，保持反射镜部分和压电元件之间的接触，因此保持对压电元件的导电。
