For 3D measurements using spectral interference of chirped optical frequency comb, the coherent link method was applied to the one-shot 3D measurement method by combining phase information in addition to the conventional measurement using amplitude information. The results showed that the measured values obtained from the amplitude and phase information were within the designed range, therefore the principle of wide dynamic range one-shot 3D measurement with nm-level measurement accuracy by coherent link using optical frequency comb was demonstrated.
