A micropositioning flex stage and its computer closed-loop control system have been developed for microfabrication and micromeasurement. It is desinged that only a single table moves on an X-Y plane.The stage is driven by on electrostrictive positioner. Positioning of the stage is carried out with a closed-loop control system using a double frequency laser interferometer measurement device. A±0.03μm positioning accuracy
