New method for real time surface cleanliness measurement
The measurement of the surface cleanliness is a problem of great importance in many industrial and technological processes. Existing methods are based on laboratory procedures, they are not performed in real time, they cannot be automated, and usually they are restricted to a small portion of the sa...

The measurement of the surface cleanliness is a problem of great importance in many industrial and technological processes.
