摘　　要：针对双光栅衍射消色散成像实验现有图像处理程序要求图像对称造成的实验操作难、测量误差大的问题,通过分析图像数据在计算机中的存储情况,提出了改进算法,该算法可实现非对称实验图像的处理,降低了实验操作难度,提高了实验测量精度.The existing image processing program for double-grating diffraction imaging experi- ment requires symmetrical image, which causes operational difficult and leads to large errors. To solve this problem, an improved algorithm was developed through the analysis of the storage mode of image data in computer. The algorithm could handle asymmetric experiment image. It reduced the difficulty of experimental operation and improved the accuracy of measurement. It was helpful for the populari- zation and application of the double-grating diffraction imaging experiment.
