| Description | We propose a method for computing an approximate (Bonferroni type) confidence interval for the distance of two micro- and/or nanostructures considered in dimensional metrology, e.g. grating lines, using data obtained by a length comparator, which allows to determine the coordinates of the edges, the position and the width of the structure from its photometric profile together with the related uncertainty contributions. The implementation is demonstrated using data obtained by the Nanometer Comparator operated at the PTB Braunschweig, Germany. |
