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 double-slit ghost imaging after second-order correlation, laying a good foundation for applications in imaging resolution and other aspects.
