Dispersive interferometry ranging with optical frequency comb (OFC) has shown great advantages in distance metrology for its simple structure, high accuracy and the ability to resist disturbance. In this paper, the principle of optical frequency comb dispersive interferometry ranging is analyzed theoretically, and various data processing methods or system improvements proposed by researchers are summarized. The resolution, precision, none-ambiguity range and other parameters of dispersion interference ranging systems are analyzed quantitatively and qualitatively. According to the analysis, the shortcomings of current methods are pointed out and the possible solutions are provided. At last, the prospects of instrumentation and application in the future are also given.
