Paper Abstract

Several mathematical methods of center evaluation of laser spot on a surface measured by the light-cut profile meter are described and analyzed. All these methods are implemented in the light-cut profile meter software and compared from the point of view of uncertainty measurement minimization. A novel method of center evaluation based upon approximation of laser spot intensity distribution by polynomial of second order is also introduced. Experimental results have shown, that this method gives the best results from the point of view of measurement uncertainty minimization.
