An assistance system for the selection of sensors in multi-scale measurement systems

Optical inspection using multi-sensor multi-scale systems requires the selection of proper sensors, their parameters (e.g. resolution, N.A, lighting conditions), and measurement strategies. We propose an assistance system that automatically selects the suitable sensors and their parameters for an inspection specification. The specimen and the defects are described based on their properties (e.g. geometry, material etc) to the assistance system. The system then uses different "sub-assistants", each designed for a specific measurement technique, to recommend the most suitable measurement setups. The system and initial results for fringe projection techniques are presented.
