An optical interferometric method has been used to measure the static surface deformations caused by a point-focused cw laser. Experiments carried out in Plexiglass show that one can guess for defects or inhomogeneities under the surface through the topography of these deformations.

    Anisotropic surface deformations appear in AgAsS[sub 2] chalcogenide films when exposed to linearly polarized 2.0 eV light spots with diameters of 5-200 μm. The anisotropic shape reflects the polarization direction. The shape also changes with the direction of light incidence. Illumination on...

    Inhomogeneity of the microplastic strain rate (deformation jumps) of a biomorphic SiC/Al composite under uniaxial compression has been studied by laser interferometry on the nanometer level. The value of strain rate jumps has been calculated from the deviation of the form of separate beats in...

    An optical feedback interferometer has been used as a sensor for measuring the deformation of the beams under dynamic loading. The compactness, non-contact nature, high accuracy (below half wavelength of the laser) and the cost-effectiveness of this sensor makes it a suitable choice for material...
