摘　　要：给出一种新的实验方法观察散斑光场的干涉条纹．实验中用强度关联测量町以观测到非相干光的鬼干涉、鬼成像和亚波长干涉，而我们在实验中直接用强度测量的方法来观察散斑光场的相干性，亢接将强度叠加得到了类似双缝干涉的图样，并给出了理论解释，理论分析的结果和实验得到的图像相一致．This paper proposed a new experiment to observe interference fringes of the speckle field： Experi： ments using intensity correlation measurement can measure ghost imaging, ghost interference and sub- wavelength interference with incoherent light. We use the intensity measurement method to observe the speckle light field coherence directly, Superposition of the intensity was similar to the double - slit interference pattern, and a theoretical explanation was given. The results of theoretical analysis are consistent with the experimental results.
