摘　　要：关联成像和关联干涉现象是当今研究的热点之一,但以干涉为出发点的研究往往较少。基于关联函数的性质介绍二阶关联成像基本理论,对双缝干涉进行鬼成像模拟。此外,当两条光路的入射波长不同时,双缝干涉的鬼成像表现出了较规律的行为。这说明参考光路中波长对关联信息的影响较大,信号光路中的波长对关联结果的影响较小,这给鬼成像实验照明光源的选择提供了一个参考依据。最后对二阶关联函数的关联特性进行了研究,对双缝鬼成像进行二阶关联运算后会出现干涉现象,这为在成像分辨率等方面的应用奠定了良好的基础。Correlated imaging and interference is currently a topic of intense research interest.However,research based on interference is limited.This study introduces the basic theory of second-order correlation imaging based on the properties of correlation functions and simulates the ghost imaging of double-slit interference.In addition,when the incident wavelengths of the two optical paths are different,the ghost imaging of double-slit interference exhibits more regular behavior.This observation indicates that the wavelength in the reference optical path significantly impacts correlation information.In contrast,the selected wavelength in the signal optical path has a relatively small impact on the correlation results.This provides a reference for selecting lighting sources for ghost imaging experiments.Finally,the second-order correlation function’s correlation characteristics were studied,and interference behavior occurred in doubleslit ghost imaging after second-order correlation,laying a good foundation for applications in imaging resolution and other aspects.
