查询词典 phase shift analysis

Theoretical analysis demonstrates that the phase change caused by the shift of illuminated light is ignored in discussion before.In this study,this method is corrected by overlapping a phase factor and a new method is put forward to eliminate the effects of this factor by utilizing the phase characteristics of squared Bessel function.
