One of the widely used techniques is laser reflectance interferometry (LRI) which enables non-contact measurement during CVD deposition. The authors have built a novel LRI system with a 405 nm laser diode which achieves better resolution compared to the systems based on He-Ne lasers, as reported so far. The system was used for in situ monitoring of thin, microcrystalline diamond films deposited on silicon substrate in PA-CVD processes. The thickness of each film was measured by stylus profilometry and spectral reflectance analysis as a reference. The system setup and interferometric signal processing are also presented for evaluating the system parameters, i.e. measurement uncertainty, resolution and the range of measurable film thickness.}, type={Artykuły / Articles}, title={Laser Reflectance Interferometry System with a 405 Nm Laser Diode for in Situ Measurements of CVD Diamond Thickness}, URL={http://www.journals.pan.pl/Content/90177/PDF/Journal10178-VolumeXX%20Issue4_02.pdf}, doi={10.2478/mms-2013-0046}, keywords={interferometry, thin films, CVD, diamond, in situ measurements}, }
