Description	Several methods of scale non-linearity measurements of Michelson interferometers have been presented but their uncertainty is comparable approximately with the total resolution of the interferometers. We developed and experimentally verified a new method where order-times smaller uncertainty of the distance measurement is possible. The method takes advantage of a direct conversion of the relative changes of the optical path in measuring arm of the Michelson interferometer to relative changes of the resonant optical frequency of the Fabry-Pert resonator. Frequency changes of the resonator have been monitored by a beat-frequency comparson between tunable semiconductor laser and HeNeI.sub.2./sub. optical frequency standard at 633 nm.
