After analyzing and processing the grating reticle image collected by CCD, the mapping coefficient can be accurately calculated from grid size to pixels. Comparing the fore-and-aft two grating reticle images after the worktable moved. Adopting phase difference ratio arithmetic based on Lissajous figures,the phase difference of two images will be figured out. The displacement of the worktable can be further calculated by the mapping coefficient.
