Abstract
A simplified realization for the Gaussian filter in surface metrology is presented in this paper. The sampling function sinu/u is used for simplifying the Gaussian function. According to the central limit theorem, when n approaches infinity, the function (sinu/u)^n approaches the form of a Gaussian function. So designed, the Gaussian filter is easily realized with high accuracy, high efficiency and without phase distortion. The relationship between the Gaussian filtered mean line and the mid-point locus (or moving average) mean line is also discussed.Proceedings Title
