Paper Abstract

An apparatus for measuring the topographies of complex surfaces with high accuracy by curvature scanning has been setup. For this purpose, a new type of curvature sensor that processes information from a relatively large area of the surface under test is moved along the surface. The principles advantages and a technical realization of this method referred to as large-area curvature scanning will be presented.
