Title:A Laser–Speckle Correlation Technique for Thickness Determination of Optically Thin Transparent LayersAuthor(s):Johannes Lettner, Bernhard ZagarAbstract:We present a method determining thicknesses of thin polar liquids on rough surfaces. Results of the reproducibility of measurements of coatings down to the $\mu$m range, which is less than the surface roughness are shown.Booktitle:Proceedings of the Frontiers in Optics/Laser Science XXVII 2011 ConferencePage Reference:2 page(s)Publishing:10/2011
