Materiology of mouldings for automobile industry
Mandát, Dušan ; Pech, Miroslav ; Hrabovský, Miroslav ; Pochmon, Michal ; Rössler, T.
This article treats of optical methods, that investigate defect of mouldings designed for automobile industry. We use simple optical system and image processing algorithm to measure surface deformation. The sources of defect usually are: scratch, bulge, grey, bristle etc.
Selected laser technologies in education of students of physical fields of study
Lapšanská, Hana ; Chmelíčková, Hana ; Schovánek, Petr ; Hrabovský, Miroslav ; Kainzová, V. ; Halenka, V.
This contribution informs about the increasing usage of laser systems in various industrial applications. In the light of this development, it is essential to update current lectures. Students of the physical and technical fields of study should improve their knowledge of basic sorts and principles of laser technologies, which they can come across in their future practice. Our laboratory is equipped with high power laser system, therefore we are able to provide students with experimental work apart from a theoretical presentation.
Evaluation of mechanical properties of thin films and coatings by the system NanoTest™ NT600
Čtvrtlík, Radim ; Stranyánek, Martin ; Boháč, Petr ; Jastrabík, Lubomír ; Hrabovský, Miroslav
This article deals with evaluation of mechanical properties of thin films and coatings by the system NanoTest™ NT600.
Review of the topographic and profilometric methods developed in the Joint laboratory of optics in Olomouc
Rössler, T. ; Mandát, Dušan ; Hrabovský, Miroslav
The presented paper is dealt with the methods of the optical 3D measurement of the shape of objects. Generally, optical methods are employed especially for the possibility of contact-less measurement. The presented mehods are the shadow and projection moiré topograpy and the computational, Fourier and stereoscopic profilometry.
Phase analysis using Fourier transform profilometry
Mandát, Dušan ; Rössler, T. ; Hrabovský, Miroslav
The profilometry method used here is the Fourier-Transform Profilometry Method that was originally published by Takeda in 1982. The geometry of the experiment is very similar that used in Moiré Topography, but the advantage of this method is only one image of the projected grating is necessary to produce the resulting object´s fringes.
Hardness measurement of inhomogeneous plasma sprayed coatings
Čtvrtlík, Radim ; Stranyánek, Martin ; Boháč, Petr ; Jastrabík, Lubomír ; Ctibor, Pavel ; Hrabovský, Miroslav
This article deals with an examination of mechanical properties of TiO.sub.2./sub. plasma sprayed coatings using nanoindentation method DSI and measuring instrument NanoTest 600 TM.
Non-contact measurement of specific elongation of the rubber specimen by means of properties of speckle correlation
Wagnerová, Petra ; Horváth, Pavel ; Šmíd, Petr ; Hrabovský, Miroslav
This paper presents the usage of speckle correlation for the measurement of specific elongation of rubber specimen.
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.
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.
