Roughness measurement with laser profilometry
Mach, Radoslav ; Frk, Martin (referee) ; Hejátková, Edita (advisor)
The bachelor thesis deals with technology of laser profilometry for material roughness measurements purposes. The theoretical part deals with all aspects of the issue in an effective way and highlights the essential characteristics of used components and material roughness. The focus of this work is in first step to describe the external factors affecting the visual image processing such as increasing of environment temperature and its effect for a camera sensors. And particularly the relationship between CMOS and CCD technologies. The second step is for measuring roughness parameters of materials, such as metal, wood, rubber and plastic with three different lasers. Results demonstrate correlation between the wavelengths of the used laser lights with particular materials.
