Abstract：A new technique of subdividing the Moire fringes to measure the interval between grating lines was adopted in large scale, with the characteristics of high resolution and evendistributed pixels of linear CCD. The circuit was also simplified since the subdividing and digitizing functions were completed by CCD simultaneously. Moreover, the subdividing multiple was so high and up to thousands of times.
