Description:

The authors analysed so-called light-cut method which is suitable for the quick and accurate measurement of the profile. The main attention is paid to mathematical methods of evaluation of the laser spot centre on a measured surface. A novel method of centre evaluation is based upon approximation of laser spot intensity distribution by polynomial of second order. This method gives the best results from the point of view of minimizing measurement uncertainty. and Autori analyzovali metódu svetelného rezu, ktorá je vhodná pre rýchle a presné meranie profilu. Hlavná pozornosť je venovaná matematickým metódam vyhodnotenia stredu laserovej stopy na meranom povrchu. Nový spôsob vyhodnotenia stredu je založený na aproximácii rozloženia intenzity laserovej stopy polynómom druhého rádu. Tento spôsob dáva najlepšie výsledky z hľadiska minimalizácie neistoty merania.
