Abstract:
1. An apparatus, comprising: a roughness sensing system comprising a 1D-, 2D- or 3D-scanning system and having a parallelogram configuration; a roughness measurement sensor including a probe pin having a slide element comprising a scan-slide element located at an end of the probe pin and a probe tip integrated with the probe pin at a predetermined distance from the scan-slide element; and an advancing device adapted to jointly move the probe pin together with the scan-slide element and the probe tip over a surface to be scanned; wherein the roughness sensing system provides (a) a first signal that allows a conclusion on the shape or geometry of a scanned surface , and (b) a second signal that allows a conclusion on the roughness of said scanned surface; said apparatus being further configured to at least one of spatially and temporally correlate the signals to align the signals at least one of spatially or temporally.
