The combination of fast defect detection by means of a line scan camera and a classifier has stood the acid test of practical application. The subsequent step of quantifying defects (especially the height of points of impact) has always been a manual process either by tactile or confocal measurement. The retrieval and the positioning of the defect in the confocal microscope took up most of the time. The associated logistic challenges and continuity and traceability of data are complex.
By combining defect detection and defect measurement in a common positioning unit and transformation of coordinates, a manual step that takes up much time and makes parts difficult to trace is eliminated. The user receives quantitative information that would otherwise take 20 minutes or more to generate, in a matter of seconds. In contrast with the established optical measurement method (confocal technology), ROLLERinspect does not scan surfaces point by point or line by line, but scans area. Thanks to the upstream Neurocheck defect detection system, defects once detected can be quantified without loss of time.
