Testing of the scale linearity of the corrected homodyne interferometer by the femtosecond comb and optical resonator

摘要：

　　The work presents a method where the change of the length of the measuring arm of the Michelson interferometer is monitored by the cavity length of the optical resonator.The resonator works as distance-to-optical frequency converter with ultimate linearity.It has locked a tunable laser to certain cavity mode.The optical frequency of the laser is heterodyned with immediate “tooth of the femtosecond comb spectrum.The results of measured scale linearity of the homodyne interferometer for corrected and non-corrected scale are presented for measuring range of the homodyne interferometer in order of one micrometer and more.
