Self-introduction
My main research interest is in the 3D metrology for the motion of a mechatronics system in manufacturing industries, namely machine tools and industrial robots. I also have works on the measurement and the control of machining processes, and geometric measurement of manufactured products. See my personal homepage above for further information about my research works and publications.
