Originální abstrakt

The work is oriented to development of the absolute distance interferometer with a narrow-linewidth tunable VCSEL laser (Vertical-Cavity Surface-Emitting Laser) at 760 nm and a wavelength-scanning interferometry technique improved by an amplitude division of interference fringe. This laser performs the mod-hop free tuning range up to 1.4 nm and a value of the injection current controls the wavelength. With respect to a high-sensitivity of the emitted wavelength to the injection current fluctuation, we provided the stabilization of laser frequency by means of an electronic frequency lock to modes of the Fabry-Perot glass etalon. Instantaneous values of the interference phase before and after the scanning process are recorded for a longer interval due to data averaging. For the first laboratory experiments, we have measured preliminary results with relative uncertainty of absolute distance measurement at 8.10-5 level.
