    Abstract

    In this paper we present a novel system concept for large scale flatness and dimensional measurement applications. This system has several advantages over traditional projection moire systems. The system has a robust optomechanical structure which avoids the tight mounting tolerances seen in current projection moire implementations. This means that the system concept will be more applicable to installations in a hostile production environment, at lower cost. The system can be installed close to the object under measurement and produces a good quality moire signal on variable surfaces including impurities, texture, markings etc. The competitiveness of the flatness measurement system is increased by building a multipurpose system and adding such measurements as edges, width or surface quality to the same unit.
