Měření otěru kyčelního implantátu metodou Fourierovské profilometrie s užitím postupného vykreslení mřížky
Pochmon, Michal ; Rössler, T. ; Mandát, Dušan ; Hrabovský, Miroslav ; Gallo, J.
Contribution is focused on possibility of using Fourier profilometry for measuring of the abrasion of cotyle implant, which is caused by using in the patient´s body. The projected optical structure in Fourier profilometry is sinusoidal pattern. The results showed, that sinusoidal pattern is not optimal optics structure to get sufficiently precise results. Instead of it, the linear pattern made by sequential drawing of linear strips can be used.
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.
