A Homodyne Quadrature Laser Interferometer for Micro-Asperity Deformation Analysis

A Homodyne Quadrature Laser Interferometer for Micro-Asperity Deformation Analysis

We report on the successful realization of a contactless, non-perturbing, displacement-measuring system for characterizing the surface roughness of polymer materials used in tribological applications. A single, time-dependent, scalar value, dubbed the collective micro-asperity deformation, is extrac...
