Optical measurement of surface topography pdf
WebThere is now a wealth of new optical techniques on the market, or being devel-oped in academia, that can measure areal surface topography. Each method has its strong points … WebOptical areal surface topography measuring instruments are powerful and flexible tools of a complex design, which makes them difficult to calibrate. Because the calibration process is an essential part of quality control during production it is very difficult for an industrial user to exploit the benefits of these instruments.
