Description
| - Je prezentován nový přístup k měření drsnosti povrchu založený na použití digitální dvouvlnové holografické interferenční mikroskopii se syntetickou vlnovou délkou. Dva hologramy náhodně drsného povrchu jsou postupně při dvou vlnových délkách zaznamenány CCD kamerou. Digitální součet obou hologramů je numericky rekonstruován. Rekonstruované digitální vlny spolu numericky interferují. Parametry měřeného drsného povrchu mohou být určeny z tvaru proužků ve vzniklém digitálním interferogramu. Rozsah měřitelné drsnosti povrchu je určen syntetickou vlnovou délkou, která je nepřímo úměrná rozdílu použitých vlnových délek. (cs)
- A new approach to surface roughness measurement based on the digital two-wavelength holographic interference microscopy with the synthetic wavelength is presented. Two holograms of a rough surface are recorded step by step at two wavelengths of laser light by means of a CCD camera. Both holograms are numerically superposed and then reconstructed. Two reconstructed digital waves obtained numerically interfere. The surface roughness parameters can be determined from the shape of interference fringes in that interferogram created. The range of measurable height irregularities of the surface is given by the synthetic wavelength, which is indirectly proportional to the difference of the selected wavelengths.
