    摘要: The present invention relates to absolute distance measurement method and system using an optical frequency generator. The absolute distance measurement method using the optical frequency generator includes (a) generating a plurality of different stabilized wavelengths by using the optical frequency generator; (b) obtaining an initial estimation value of a distance to be measured by using a frequency sweeping interferometer; (c) analyzing an uncertainty range of the obtained initial estimation value; (d) measuring excess fraction parts of the different wavelengths by analyzing interference signals for each of the wavelengths; (e) determining integer parts for each of the different wavelengths within the uncertainty range of the initial estimation value; and (f) measuring an absolute distance to be measured by using the excess fraction part and the integer parts for each of the different wavelengths.
