Profilometer for testing sandpaper? (post #92577)

Does anyone remember a previous article where a profilometer was usesd to test sanpaper and scratch patterns.  I seem to remember an old article where this was done, but I could be wrong.

I did a search at FWW.com subscription site and found only one hit for profilometer -- it was in an Chris Minick article about water-borne finishes.  If you're a member, you can access it here.  If not, it's in Nov/Dec 2006.

This one? Any research library should be able to get a copy for you for a nominal fee.

Lemaster, Richard L.: "Hardwood machining R&D: Surface quality and process monitoring technologies", Proceedings of the Conference on Eastern Hardwoods, Resources, Technologies, and Markets, 1997, p 109-120, Apr 21-23 1997, Harrisburg, PA, USA
Abstract: [...] This paper focuses on surface quality measurement research and reviews work to date to develop an optical surface profilometer which utilizes surface quality evaluation as a process monitoring tool. In most cases, wood machining processes are heavily influenced by workpiece surface quality considerations. Tool sharpness requirements as well as machine feed and speed decisions are often based on workpiece surface quality. Research in surface measurement technology is being aimed at identifying and quantifying defects associated with a variety of machining processes. Surface waviness is often introduced by the machining process or by the vibration of the tool or workpiece, whereas surface roughness is often introduced by the detachment of material from the workpiece. Of particular interest in this research is the use of frequency domain analysis to separate the random from the periodic components of the surface. The optical profilometer surface measurement system discussed in this paper has been found to be effective for identifying surface defects including surface waviness, torn grain, fuzzy grain, and abrasive (sanding) grit marks.
