| Description
| - Práce je orientována na vývoj absolutního interferometru pro měření vzdálenosti s laserovou diodou typu VCSEL (Vertical-Cavity Surface-Emitting Laser), která se vyznačuje především velmi úzkou šířkou spektrální čáry a možností plynulého ladění vlnové délky. Při konstrukci byla využita VCSEL dioda s vlnovou délkou 760 nm. V laserovém interferometru je využito detekční techniky WSI (Wavelength-Scanning Interferometry), která je navíc vylepšena pomocí techniky amplitudového dělení interferenčních proužků. VCSEL diody jsou známy také svou zvýšenou citlivostí na stabilitu proudového zdroje a teplotu. Z tohoto důvodu byl využit Fabry-Perot rezonátor a pomocí zpětné vazby byla laserová dioda zamknuta na jednotlivé módy tohoto rezonátoru. Při prvních experime ntálních měřeních bylo dosaženo přesnosti 8.10-5. (cs)
- 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.
