    摘要： A variable shape mirror includes a support substrate provided with a conductive bonding portion that is divided into two areas bonded to a lamination type piezoelectric actuator. A bonding surface of the piezoelectric actuator is provided with a first metal film that is divided into a first area and a second area that are not connected to each other electrically. Side faces of the piezoelectric actuator are provided with a second metal film that connects a first common electrode to the first area electrically or connects a second common electrode to the second area electrically. The piezoelectric actuator is disposed on the bonding portion so that the individual areas of the first metal film are connected electrically to the different areas of the bonding portion, respectively.

    摘要： In a variable shape mirror including a base substrate; a mirror with a mirror surface; a fixed part, arranged on the base substrate, for fixing the mirror and the base substrate; and an actuator using a piezoelectric ceramics arranged between the base substrate and the mirror; an initial voltage of the actuator is a negative voltage. The initial voltage differs for each actuator; and is larger than or equal to a voltage at which a displacement of the actuator becomes minimum and smaller than zero voltage. The negative initial voltage is a bias voltage, and a voltage stroke is performed while applying the bias voltage.

    摘要： A variable shape mirror includes a support substrate, a mirror substrate that is opposed to the support substrate, a fixing member that is disposed on the support substrate and fixes the mirror substrate, and a piezoelectric element that is disposed on the support substrate and is expanded or contracted so as to deform a reflection plane of the mirror substrate. A bonding layer for bonding the mirror substrate and the fixing member to each other is provided to the surface of the mirror substrate opposite to the surface on which the reflection plane is formed, and the bonding layer is formed in an area that corresponds to the outside of an incident area of a light beam that enters the reflection plane.

    摘要： The variable-shape mirror is provided with a support base and a minor portion that is disposed to face the support base and that has on a side thereof facing away from the support base a minor surface which is irradiated with a light beam. There are also provided piezoelectric elements that are sandwiched between the support base and the mirror portion and that vary the shape of the mirror surface. The piezoelectric elements are bonded, through a thin layer of metal that is separately provided for bonding, to at least one of the support base and the mirror portion. A driving voltage to the piezoelectric elements is supplied through the thin layer of metal.

    摘要： In a variable-shape mirror (1) of which the shape of the mirror surface can be varied, four piezoelectric elements (4) are sandwiched between a support base (2) and a mirror portion (3), and are arranged symmetrically in cross-shaped directions. The piezoelectric elements (4) are bonded to the mirror portion (3), and serve both to vary the shape of the mirror portion (3) by being driven and to fix the mirror portion (3) to the support base (2). Support portions (5) are arranged one inside each of the piezoelectric elements (4). With this structure, a small movement that the piezoelectric elements (4) produce when driven can be converted into a large movement of the mirror portion (3).
