This paper introduces a new method for measuring position with CCD. This method is different from other optical systems for position measurement. By designing a special optical system with two linear array CCDs, two dimension position coordinates can be high precisely measured. In this paper, the measurement error of this optical system is analyzed and this system is proved to have a high precision. This two dimensional position measurement method with two linear array CCDs has some advantages: fast response, high accuracy and low cost. So, this method has a good future to apply in industry because of its attractive performance/cost ratios.
