Application studies for fluorescence-based indirect optical geometry measurement

Is there an optical measuring system that can be used to precisely determine the geometry of all types of components, i.e. for all current and future materials?

This question is to be answered within the framework of a highly topical European research project. The underlying idea is that the surface is not measured directly, but indirectly via the imprint in the surrounding liquid or air. The fluorescence effect is used for the optical recognition of the environment. As a result, this innovative approach promises universal applicability for the first time, both for highly reflective and highly absorbent materials.

The aim of the work is to develop the application potential of the new measuring principle. To this end, the measurement system is to be tested experimentally for different materials and component shapes, the model-based signal evaluation is to be continuously expanded and the measurement results are to be evaluated. In addition, it will be investigated how the measurement time can be minimised.
