An optical measurement method is developed to overcome this challenge. This method, relying on angular reconstruction of scattered light profiles, is used for the measurement of irregular wear in quality testing of round surfaces which provides information on estimating the surface lifetime after prolonged use. This approach achieves a 3D depth accuracy better than 50 mu m in suspension bars with diameters up to 50 mm from an imaging distance of 250 mm.eninfo:eu-repo/semantics/openAccess3D optical measurementdigital image processingrodwearnon-invasive measurementConference ObjectQ41354746748WOS:000481717100051
