| Abstract: | The lateral positional deviation between virtue image and original object in the bi-grating imaging process has been studied by using grating equation and bi-grating imaging equation.The expression of the lateral positional deviation is given and the influencing factor of positional deviation is analyzed.The influence of grating parameter has been discussed,and the relational graph is given.Some characteristics of the excursion have been analyzed qualitatively,and some of useful conclusions are obtained. |
