Paper Abstract

High-accuracy long-distance is performed using a broad and stable femtosecond frequency comb. Cyclic-error, which has been the main source of inaccuracy in conventional measurements, is reduced more than tenfold, directly achieving high accuracies of 50 μm at 1-GHz frequency and 14 μm at 10-GHz frequency in a 240-m distance measurement using the phase measurement of intermode beats of a femtosecond frequency comb. Traceability of distance meters is discussed.
