摘要
结合科研新成果，对现有的光栅衍射实验的改革与创新进行了探索，提出了基于双光栅衍射成像的新实验方案，对实验的具体内容、所需的仪器及实验难度进行了分析和讨论，使其成为一个既能说明基本的衍射现象，又能使学生全面认识光栅衍射特性的新型衍射光学实验。
The innovation scheme for the experiment of grating diffraction based on the new phenomenon of bigrating imaging effect is presented. The experimental method and content are given and the experimental difficulty is analyzed. Combined with the character of the experiment of undergraduate course, the experimental device is designed and its practice operation is discussed. The new experiment not only shows fully basic dif fraction phenomenon, but also helps students to get deep understanding for grating diffraction properties.
