Abstract
To satisfy the need of precision displacement, a 3D Nano driving system, which including metrological vertical scanning system and coplanar 2D precision stage with large-stroke and nanopositioning resolution, is developed in this paper. The coarse-fine dual-stage actuators have been applied in the 3D Nano driving system in X, Y and Z directions. The servomotors combining with precision lead screws and linear guides are used to actuate the coarse driving, and piezoelectric actuators combining with parallel board flexure hinges are used to actuate the fine driving. Three laser interferometers are used to measure the displacement in X, Y and Z directions respectively. The structure and principle of the system is introduced and the displacement range and displacement resolution of the system are also analyzed in details. The 3D Nano driving system has been successfully applied in the white light interference based atomic force probe scanning measurement system for ultra-precision surface topography developed in our laboratory. The experimental results show that the nano-driving in X, Y, Z directions can be realized by the 3D Nano driving system.
