Laser cladding with a numerical modelling of the temperature field in material utilization
Stranyánek, Martin ; Chmelíčková, Hana
Laser cladding is presented as a one of the technologies of laser material surface treatment. A series of speciments have been treated using CO.sub.2./sub. laser with a maximum output power of 2.5 kW by this technology. Some characteristics and properties such as shape or microhardness of clad layers were analysed. For numerical calculations of the laser induced temperature field in treated material was used the finite difference method.
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.
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.
Similarity of interference and holographic interferometry with moiré phenomena and possibility of use for modelling
Rössler, T. ; Hrabovský, Miroslav
The paper is devoted to modeling of two know effects, interference and holographic interferometry using another phenomena, colled the in-plane moiré. Although every method has various physical priciple and the result intensity patterns have various properties the generalized definition of moiré phenomena helps to find out the similarity between them.It is the similarity of shapes of intensity patterns.
