Using two electro-optic modulator-based optical frequency comb sources, we demonstrate an optical
frequency comb interferometer that enables rapid and precise measurement of over long distances.
500 kHz is the repetition rate of the relative measurement of a 6-mm ambiguity range. The repetition
rate of an absolute distance measurement is about 15 Hz with switching modulation frequencies. The
optical frequency comb interferometer yields 0.4-μm precision at 5.2 m in 2 μs. The improved precision
exceeded 30 nm in 1 ms.
