A novel feedback system has been developed in order to mechanize laser ablation processes such as laser cleaning. This is aimed at improving the safety and productivity (cleaned area/time) of the laser treatment in all those applications where the ablation process is not self-terminated. The system, which is devised as a stand-alone equipment that can be adapted to different laser sources, is based...
A THz Time Domain spectrometer was used to investigate painting layers in reflection geometry. The stratified layers were characterized and the refractive indexes were measured. The results were used for estimating the thicknesses of superimposed paint layers.
An innovative fiber optic setup for the scattering-free absorption spectroscopy of liquids is presented. It makes use of an integrating sphere that contains the sample under test, coupled to a fiber optic supercontinuum source and to a fiber optic spectrometer. The highly-bright broadband light shining on the sphere's surface is diffusely reflected and collected by the fiber-coupled spectrometric...
