COMPARISON EXPERIMENT FOR PULSE REPETITION INTERVAL BASED LENGTH MEASUREMENT LINKED TO A FEMTOSECOND OPTICAL FREQUENCY COMB

• Abstract:

  As an alternative to the conventional method, which length measurement is performed as a function of the wavelength of a monochromatic laser source, we proposed the method of measuring arbitrary and absolute length using the pulse repetition interval of a femtosecond optical frequency comb (FOFC - the national standard tool for measuring length in Japan). A helium-neon laser evaluation system was developed for distance determination comparison experiment and its uncertainty estimation was performed in order to validate the proposed method.
