Two-color heterodyne laser interferometry for long-distance stage measurement with correction of uncertainties in measured optical distances

Abstract We designed a new system that eliminates deviations by correcting uncertainty in optical distance measurements in the laser two-color heterodyne interferometer. In simulations, eliminating the uncertainty from the atmosphere, the deviation in the uncertainty of the optical distance was 50 t...
