We inscribed surface relief grating on the thin films using Point-by-Point method and amplitude mask method (the amplitude mask was taken place by grating roll film manufactured by ourselves).

利用逐点写入法和振幅掩模法(振幅掩模板为自制光栅胶片)在这种薄膜上刻写了表面形貌光栅。

The displacement vector for surface relief was determined to be near the invariant line direction using electron back scattering diffraction method.

本工作应用背散射电子衍射技术测得产生浮突的位移在不变线方向附近。
