Absolute measurement of surface roughness.
In an interferometer which uses a reference surface, the measured surface heights correspond to the difference between the test and reference surfaces. To accurately determine the rms roughness of supersmooth surfaces, the effects of the reference surface roughness need to be removed. One technique for doing this involves averaging a number of uncorrelated measurements of a mirror to generate a...
متن کاملNon-Contact Surface Roughness Measurement by Implementation of a Spatial Light Modulator
The surface structure, especially the roughness, has a significant influence on numerous parameters, such as friction and wear, and therefore estimates the quality of technical systems. In the last decades, a broad variety of surface roughness measurement methods were developed. A destructive measurement procedure or the lack of feasibility of online monitoring are the crucial drawbacks of most...
متن کاملAverage Surface Roughness Measurement Using Photometric Stereo Method
This paper presents a technique for measuring surface roughness (Ra), using photometric stereo method. The method utilizes three or more images of the measured surface from the same view point, taken sequentially under different illumination conditions. The scenes captured by the camera were reconstructed by the least square method to obtain surface normal from surface topography. Three-dimensi...
متن کاملSurface roughness measurement using dichromatic speckle pattern: an experimental study.
Surface roughness is studied experimentally by making use of the statistical properties of dichromatic speckle patterns. The rms intensity difference between two speckle patterns produced by two argon laser lines are analyzed in the far field as functions of the object surface roughness and the difference in the two wavenumbers of the illuminating light. By applying previously derived formulas,...
متن کاملEffects of surface roughness on light scattering by small particles
Roughness exists on almost all natural particle surfaces, such as spores, aerosols, cells, etc. In this paper, we study the effects of surface roughness on light scattering for spherical shaped particles. A 3D finitedifference time domain model is used to solve for all the optical properties of the scatterer. We will introduce a roughness parameter and show its effect on the light scattering pr...
