Dispersive interferometry based on optical frequency combs has been widely applied in long-distance ranging, refractive index measurements of solids, and optical coherence tomography. In this study, we propose a theoretical model to analyze the influence of spectral resolution that can explain the relationship between the interference contrast of the interference spectrum and the variation in the measured distance with the resolution of a spectrometer. It can also be used to compensate for the systematic error caused by the resolution of the spectrometer. Our proposed model was verified experimentally, and the relative difference between the experimental and the theoretical results was less than 0.003%.
