	Spectroscopic monitoring of pulsed laser welding process Šebestová, H. ; Nožka, Libor ; Chmelíčková, Hana ; Řiháková, Lenka Real-time non-destructive defect detection is a modern approach in laser welding quality control. Usual defects like insufficient or excessive penetration can be discovered immediately during the welding process when specific characteristics of generated plasma are monitored. Detailed record
	Measurement of scattering properties of ultrathin glass mirrors Mandát, Dušan ; Pech, Miroslav ; Palatka, Miroslav ; Nožka, Libor ; Nováková, P. ; Hrabovský, M. ; Schovánek, Petr Following text deals with results of light scattering measurement of glass mirrors using the optical instrument CASI owned by Joint Lab- oratory of Optics (JLO) of the Palacky University and the Institute of Physics of Academy of Science of the Czech Republic. JLO pro- duces the large-area ultrathin mirros which are used in fluorescence detectores (FD). Detailed record
	Near UV filter optical properties Palatka, Miroslav ; Mandát, Dušan ; Pech, Miroslav ; Nožka, Libor ; Nováková, P. ; Marek, M. ; Hrabovský, M. ; Schovánek, Petr Following text notice results of measurement of optical properties of the M-UG6 filter used in fluorescence telescopes (FD). We use op- tical instruments owned by Joint Laboratory of Optics of the Palacky University and the Institute of Physics of Academy of Science of the Czech Republic. Detailed record
	Spectroscopic method for the laser welding quality control Chmelíčková, Hana ; Lapšanská, Hana ; Nožka, Libor Laser welding is a modern and flexible method of the material joining. Because many parameters are insolved in this process, some defects can occur. Research of the on-line weld quality control is curried out all over the technical world to reach nearly zero defect production to save manufacture costs and environment. Detailed record
	Zkušenosti s měřením reflexních vrstev u zrcadel používaných pro projekt Pierre Auger Pech, Miroslav ; Hrabovský, Miroslav ; Schovánek, Petr ; Křepelka, Jaromír ; Palatka, Miroslav ; Nožka, Libor ; Mandát, Dušan ; Rössler, T. ; Řídký, Jan ; Boháčová, Martina The Pierre Auger Observatory is designed for study of the universe's high energy particles, which evolve in the high layers of the atmosphere, where an elementary particle strikes with energy above 10.sup.19./sup. eV (1.6 J!). However, there is no scientific consensus about cosmic ray origin. The Auger Observatory is projected to gather the data needed to solve that puzzle. One of the detection technique is to observe these showers by fluorescent detectors, which are able to record the cascade development where the secondary particle causes atmospheric nitrogen to fluoresce.

	Světelný kolektor pro vzdušnou fluorescenci a také pro rozptyl záření na nečistotách křemíkových desek Palatka, Miroslav ; Schovánek, Petr ; Hrabovský, Miroslav ; Nožka, Libor ; Řídký, Jan ; Boháčová, Martina Air fluorescence is defined as photons produced by charged particles in the air. The excited molecules emit light in the near UV and in the visible region between 300 nm and 400 nm. The simple light collection system for laboratory analysis of the fluorescence signal is presened. The optical layout of Surfscan 4500 (KLA-Tencor) is described and very high similarity between it and fluorescence colection system is shown. Detailed record
	Image data analysis of 3D topography Mandát, Dušan ; Nožka, Libor ; Hrabovský, Miroslav This article is about 3D scanning topography. It is a new optical method that use the detection of laser trace projected on diffuse reflecting surface. Detailed record
	3-D optical scanning topography Nožka, Libor ; Mandát, Dušan ; Hrabovský, Miroslav This paper refers to the theory of new optical noncontact topographic measurement method of objects with diffuse surface. It uses laser strip made by cylinder lens to iluminate object in quastion. Detailed record
	Deformation of the mirror segments for fluorescent detector in Pierre Auger observatory by its own weight Pech, Miroslav ; Hrabovský, Miroslav ; Schovánek, Petr ; Palatka, Miroslav ; Nožka, Libor ; Vlček, Martin ; Řídký, Jan ; Grygar, Jiří The Pierre Auger fluorescent detectors are optical telescopes, mirror in the each of them is composes of 60 hexagonal ultrathin segments in gravitational field of the Earth are here presented. Detailed record
	Analysis of abrasion of cotyles Mandát, Dušan ; Nožka, Libor ; Hrabovský, Miroslav The 3D optical scanning topography is one possible method of an analysis of the cotyle deformation. The object of this experiment is to quantify the decrease of cotyle material. The scanning object is polyethylene coxa cotyle ABG1.The cotyle is a plastic fossette surounded with metal cage, which is connected with a coxa of the patients. Due to use the deformation of the surface arise. Detailed record
