OpTest's "OpTiSurf" is indeed a new way to measure surface roughness. According to OpTest, "The OpTiSurf revolutionizes the measurement of surface roughness of paper. Using advanced optics and algorithims, it quickly quantifies the optical roughness of entire sheets. OpTiSurf correlates with traditional air leak tests but has greater precision and speed, with less maintenance." And I would emphasize that no air is required.
