The principle of a unique interferometer, called a femtosecond optical frequency comb-based (FOFC-based) tandem interferometer, is proposed and demonstrated for the first time. By taking advantage of both the temporal coherence characteristic of an FOFC light source and the transmission characteristics of acquired length information based on a tandem interferometer, the present technique is expected to be useful for high-precision measurement of long distances for not only science purposes but also industry requirements.
Key words: mode-locked lasers / frequency comb / tandem interferometer / ultrafast phenomena / temporal coherence
