Meier}, country = {}, institution = {}, abstract = {Confocal spectral interferometry (CSI) is an innovative optical method for determining microtopography of surfaces and thickness of transparent layers, based on the combination of two optical principles: confocal imaging, and spectral interferometry. Confocal optical system images at each instant a single point of the sample. The whole surface is reconstructed by plan scanning. The interference signal generated by mixing two white-light beams is analyzed using a spectrometer. In this work, five ‘rugotests’ of known standard roughnesses are investigated. The topography is then measured and illustrated, and the equivalent roughness is determined and compared with the standard values. }, journal = {International Journal of Physical and Mathematical Sciences}, volume = {11}, number = {7}, year = {2017}, pages = {273 - 276}, ee = {https://publications.waset.org/pdf/10007419}, url = {https://publications.waset.org/vol/127}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 127, 2017}, }
