we described a system, which was implemented by a link between optical frequency comb and conventional optical interferometry. The object with meter order depth can be measured with micro-scale lateral resolution and nano-scale axial accuracy without phase ambiguity error by performing the spatiotemporal link between two single frequency waves in radio frequency domain and optical visible light domain. And the measurement time was also dramatically reduced.
