PRÜFUNG DER EBENHEITSABWEICHUNG MITTELS MOIRE-VERFAHREN

Abstract

The measuring device described in the paper is working by the Moire techniques using a lined grid, which sen'es simultaneously as a plane surface standard, resulting measurement pictures through Moiré lines. These lines, similar to the levellines of a map, give promptly the relief of the investigated surface. The sensibility depends from the division of the grid. The device build up as a compact table unit.
