摘　　要：根据双光栅色散-汇合光谱衍射成像系统光路与光栅方程,用Python程序语言编写了双光栅衍射成像过程的模拟实验程序。文中给出了计算式、算法流程以及图形用户界面(Graphical User Interface,GUI)的设计,所编写的程序不仅能模拟实际的双光栅色散-汇合光谱衍射成像实验,得到相关的实验数据,还能演示双光栅衍射成像过程中的光路变化与成像效果。Based on the optical system of hi-grating dispersion and combination spectrum imaging and the grating equation, a software program for the simulating experiment of bi-grating diffraction imaging is created with Python. The calculation formula, algorithm flow chart and design of Graphical User Interface （GUI） are presented. The program in this paper can not only simulate the actual bi-grating dispersion and combination spectrum imaging experiment and obtain the experimental data, but also demonstrate the changes of light path and show the quality of image in the formation process of hi-grating diffraction imaging.
