  • Actuator system for nanoscale movement
    Patent number: 7393175
    Abstract: An actuator system for making a nanoscale movement of an object is provided. In the actuator system, a platform supports the object. A Z-axis actuator connects the platform to the object in a Z-axis direction, and moves the object in the Z-axis direction by Z-axis direction transformation. A frame supports the platform around the platform. An X-axis actuator connects the frame to the platform in an X-axis or Y-axis direction perpendicular to the Z-axis, and moves the object in the X-axis direction by transformation in the direction perpendicular to the Z-axis.
