Description	In the work, we present the absolute interferometer with a narrow-linewidth tunable VCSEL laser (Vertical-Cavity Surface-Emitting Laser) working at lambda 760 nm. As a detection technique, we use a fast wavelength-scanning interferometry improved by an amplitude division of the interference fringe with using two signals in quadrature. Used VCSEL laser is wide tunable with the mod-hop free tuning range more than 1.2 nm. We control the stabilization and tuning process of the laser wavelength with using the frequency lock to a Fabry-Perot glass plan-parallel etalon with high-fines. The optical set-up of the interferometer uses polarized beams and Michelson structure of the interferometer. We experimentally compared the developed absolute interferometer with a conventional – incremental Michelson interferometer based on a single frequency He-Ne laser that has the resolution 1.2 nm. We achieved the relative uncertainty below 10-4 order for a range of tested distances L < 78; 118 > mm.
