摘　　要：In this paper, the limitations of the common method measuring intrinsic spatial resolution of the GEM imaging detector are presented. Through theoretical analysis and experimental verification, we have improved the common method to avoid these limitations. Using these improved methods, a more precise measurement of intrinsic spatial resolutions are obtained.In this paper, the limitations of the common method measuring intrinsic spatial resolution of the GEM imaging detector are presented.
