The challenge in the automated recording of particles on surfaces which are not optically smooth is that fact that the contrast between the particles and the surface is inadequate.

A regular optical measuring system is therefore unable to differentiate whether a certain structure belongs to the surface or whether it has been caused by a particle.

To solve this problem, a measuring technique has been developed at the Fraunhofer IPA in Germany, which is based on the use of glancing light to illuminate surfaces.

This form of illumination works like a filter: the rough technical surface is faded out, the particles become clearly obvious. This reproducible technology is integrable and automatable.

The image produced by the streaking light technology contains enough contrast, to measure the particular contamination on technical surfaces directly by the image processing routines.

The examination of the surface for thin film deposits is based on the relative change of luminace evoked from a thin filmy layer on the surface. A reference value is simple carried out on a defined surface. Conclusions about the film depositions can than be easily performed in comparing measurements. Film depositions like e. g. oil, grease, cooling lubricant or corrosive protection can be easily detected.

A variable threshold can be set to return a "reject part" (nIO) and "good part" (IO) statement about the test item.
