Abstract:  As the rapid development of IC and MEMS industries, ultra|precision positioner has become a fundamental equipment for their applications. It has been a big challenge to improve the measurement accuracy and the positioning accuracy of positioner.  A brief introduction is given to the scheme of ultra|precision positioner and common measuring systems of it, and a new measuring device|surface encoder (2D encoder) is narrated in details. 
Key words:  ultra|precision positioner; measurement system; surface encoder
