Paper Abstract

The work is oriented to development of methods for the absolute laser interferometry. The difference between absolute and incremental measurement is described. In the field of the absolute laser interferometry, the linewidth of the laser source limits the maximum measurable distance and the interval of mode-hop free tuning range determines the resolution of the distance measurement. Then, is work is oriented to selection of the primary laser source for the absolute laser interferometry and to determination of its characteristics. Methods of measurements and calculation of basic parameters of the tunable lasers are well described. The method of the absolute laser interferometry with wavelength-scanning interferometry technique improved by an amplitude division of interference fringe was designed and it is described. The Fabry-Perot etalon was designed and it is used to measure the tuning range ofthe laser source.
