Noncontact measurement of a small rotation of object by means of a speckle correlation
Horváth, Pavel ; Bača, Zdeněk ; Hrabovský, Miroslav ; Bačová, L.
This work builds upon the general theory of determination of an object deformation tensor by means of the method availing the statistical property of speckle in an optically free space.
Waveguiding ZnO and BaTiO3 thin films fabricated by laser deposition
Jelínek, Miroslav ; Kocourek, Tomáš ; Mazingue, T. ; Escoubas, L. ; Flory, F.
Various deposition configurations for deposition of large area homogenous films (3x3c 2 ) were studied. High quality ZnO and BaTiO3 films were deposited by KrF laser ablation. Optical properties by method of mode spectroscopy were measured.
Nanokrystalické diamantové vrstvy deponované hybridní pulsní laserovou depozicí
Novotný, Michal ; Jelínek, Miroslav ; Bulíř, Jiří ; Lančok, Ján ; Vorlíček, Vladimír
We used pulsed laser deposition (PLD) and hybrid PLD (HPLD) techniques for NCD thin films preparation. KrF excimer laser beam (Lumonics, .lambda.=248 nm , 20 ns, 500 mJ) was focused on graphite target with energy density of 4-7 J.cm.sup.- 2./sup.. Films were deposited on sapphire and Si(100) substrates in hydrogen and argon/hydrogen ambient
Laserové řezání CVD diamantových plátků
Chmelíčková, Hana ; Stranyánek, Martin ; Rosa, Jan ; Vaněček, Milan
CVD diamond wafers with diameter 51 mm and thickness from 0,1 mm to 0,7 mm are necessary to cut to different shapes. Cutting technology by means of pulsed Nd:YAG laser was developed to successful dividing of thin pieces
Výsledky mikroanalýz Ni-Cr-si struktur laserových povlaků
Stranyánek, Martin ; Chmelíčková, Hana ; Hrabovský, Miroslav
Studied structures were produced by Ni-based alloy laser cladding on ČSN 411 373 steel using CO.sub.2./sub. laser. Some verification of process parameters and material distribution in clad layer were analysed by SEM
Study on material composition in the layer of coat produced by laser
Stranyánek, Martin
The article deals with investigation of layers produced by the laser cladding technology from viewpoint of material changes in treated area. The elements distribution was studied by scannig electron microscopy.
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.
Digitální projekční moiré topografie se dvěma projektory
Rössler, T. ; Hrabovský, Miroslav ; Pluháček, F.
The double-projector moiré topography is a well-known optical topografic method based on the projection of the shadow or light gratings onto the measured object under various angles. There can be observed except these projected gratings another structure on the record image of result intensity field. Thanks the development of computer techniques it is possible to apply another procedure.
The evaluation of the dentine surface by means of SEM & AFM after previous exposure to Nd:YAG laser
Novotný, R. ; Zapletalová, Z. ; Kubínek, R. ; Chmelíčková, Hana ; Peřina st., Jan
Dentine sensitivity is a common complaint of patients in dental offices. It is caused by the opening of dentine tubules towards the external environment. One of the procedures that seems to have a longer-lasting effect is the closure of the exposed dentinal tubules on the teeth surface by means of CO 2 laser or Nd:YAG laser.
The evaluation of the dentine surface by means of SEM & AFM after previous exposure to ND:YAG laser
Zapletalová, Z. ; Peřina st., Jan ; Novotný, R. ; Kubínek, R. ; Chmelíčková, Hana
Dentine senzitivity is a common complaint of pacients in dental offices. They are caused by the opening of dentine tubules. This may be due to enamel or cementum loss or due to the dentine exposure in the area of cementum-enamel junction. A procedure with long-lasting effect seems to be the closure of the exposed dental tubules on the teeth surface by means of CO 2 or ND:YAD laser.
