2.2 Measurement Principle
The wave-scan 3 is the objective eye for a brilliant finish. It provides quality control and trou-
bleshooting for class A surfaces.
Surface appearance changes with the size and distinctness of wavy structures. The wave-scan
analyzes waviness intensity with 5 wavelength ranges (0.1 mm - 30 mm) and evaluates the bril-
liance of the surface. The results form a “structure spectrum" and help to analyze and optimize
the surface quality based on material and / or process parameters.
2.2.1 Measurement of Waviness
The wave-scan simulates visual perception. Like our eyes, the instrument optically scans the
wavy light / dark pattern. A laser point light source illuminates the specimen at a 60° angle and
a detector measures the reflected light intensity at the equal but opposite angle.
The instrument is rolled across the surface and measures point by point the optical profile of the
surface across a defined distance. The wave-scan analyzes the structures according to their size.
To simulate the human eye’s resolution at various distances, the measurement signal is divided
into several ranges of wavelength using mathematical filter functions.
