The application of functional coatings on surfaces during industrial manufacturing process is an essential part in many kind of process chains. Production auxiliary components ensure or ease an on-going production process, serve as temporary protection of the base material or act as indispensable components to secure successional manufacturing steps. Thus, a monitoring of such coating processes will have a tremendous influence on the final product quality. Beside this, and from managerial point of view, it is an important aspect to prevent production errors and interruptions at an early stage. A progress based of already established measurement technologies have led to inline/online process analysis which enable nowadays a wide use for data acquisition of auxiliary components on surfaces in a non-contact and non-destructive way with the aim of fast and efficient production control. However, such applications on wood materials revealed insuperable obstacles apparently, arising from the complexity and peculiarity of such material as natural component. The are many and different optical systems already in use in the wood material manufacturing industry and especially laser-based procedure serve mainly to measure metric units. This contribution will introduce a measurement procedure from an analytical and chemical point of view which enables to acquire, evaluate and document a surface coating status from substantial information. It opens new perspectives and paves the route for more efficient process quality assurance up to real-time process steering in the wood manufacturing industry
