Advanced Nanomeasuring Techniques for Surface Characterization

Abstract

Advanced precise and accurate nanomeasurement techniques play an important role to improve the function and quality of surface characterization. There are two basic approaches, the hard measuring techniques and the soft computing measuring techniques. The advanced soft measuring techniques include coordinate measuring machines, roundness testing facilities, surface roughness, interferometric methods, confocal optical microscopy, scanning probe microscopy, and computed tomography at the level of nanometer scale. On the other hand, a new technical committee in ISO is established to address characterization issues posed by the areal surface texture and measurement methods. This paper reviews the major advanced soft metrology techniques obtained by optical, tactile, and other means using instruments, classification schemes of them, and their applications in the engineering surfaces. Furthermore, future trends under development in this area are presented and discussed to display proposed solutions for the important issues that need to be addressed scientifically.

Fractal Analysis of AFM Images of the Surface of Bowman’s Membrane of the Human Cornea

“…Surface characterization using accurate and precise nanomeasuring techniques are important tools especially in medicine and biology to obtain high-quality threedimensional images of a surface. 2,21,41 The images are ideal to apply fractal analysis to obtain additional information on surface properties. No fractal or multifractal analysis study of the 3-D surface of Bowman's membrane of the human cornea was found in the available ophthalmologic literature.…”

Modification of surface morphology of Ti6Al4V alloy manufactured by Laser Sintering

“…Abrasive blasting leads to changes in both a surface area size and roughness parameters. The removal of the surface lay- ers and the subsurface work hardening occurs together with changes of mechanical properties and surface activity [4][5][6].…”

Three‐dimensional reconstructions of solid surfaces using conventional microscopes

“…However, the present paper is not focused on classifying various methods and devices enabling three-dimensional (3D) reconstructions of solid surfaces. Some of these techniques and devices were described elsewhere (Sezen and Fisco, 2013;Mathia et al, 2011;Ali, 2012;Czarnecki et al, 2014). The present paper discusses one of the 3D reconstructive methods that is applicable to conventional microscopes.…”
