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.
