| 摘 要： | 从光传播基本理论和光栅衍射性质出发,研究了双光栅成像效应中的光能量传递,得到了确定汇合级光强的表达式.结合双光栅成像方程,分析了两光栅的衍射性质与成像位置对汇合级光能量的影响.分析表明汇合级光强与两光栅具体的衍射效率和双光栅成像时的位置密切相关.测量了三组不同类型双光栅成像系统的汇合级光能量,实验结果和理论分析基本一致.

| Abstract: | Based on the theory of light propagation and diffraction characteristics of grating,the optical energy transfer of bi-grating imaging system is studied and the expression for the intensity of combined beams is given.Combined with bi-grating imaging formula,the influence of bi-grating properties and imaging place on intensity of combined beams is analyzed.The results show that intensity of combined beams is closely related with diffraction efficiency and location of two gratings.In three bi-grating imaging systems,the intensity of combined beams is measured.The experimental results are consistent with theoretical anticipation. |
