    摘要: In one embodiment, an actuator for positioning of mirrors in an optical system is provided and includes an actuator base and a reaction mass assembly. The reaction mass assembly includes a reaction mass support member having biasing features formed as a part thereof and a reaction mass that is coupled to the biasing features such that the reaction mass is suspended on biasing elements in six degrees of freedom (DOF). The support member is fixedly connected to the actuator base; however, the reaction mass is not directly attached to the actuator base but rather is supported in the reaction mass support member in a manner that allows it to have six DOF.

    摘要: The present invention relates to a positioning apparatus. The positioning apparatus comprises at least one position sensor, at least one position controller and at least one position actuator, wherein the or each position sensor measures the position of a position controlled device, wherein the or each position controller uses measurement signals provided by the or each position sensor as input signals, and wherein output signals generated by the or each position controller are used by the or each position actuator to control the position of said position-controlled device. The positioning apparatus further comprising gravity compensation means compensating gravitational forces acting on said position-controlled device, wherein the gravity compensation means comprises at least one gravity compensation controller and at least one gravity compensation actuator, wherein the or each gravity compensation controller uses the output signals generated by the or each position controller as input signals, thereby generating output signals used by the or each gravity compensation actuator to compensate gravitational forces acting on said position-controlled device.
