Image Transition Edge Physical Modeling Method for Exact Object Shape Position Determination
Kohoutek, Michal ; Vodrážka, Jiří (referee) ; Diviš, Zdeněk (referee) ; Škorpil, Vladislav (advisor)
Doctoral thesis is focused on a design of a new original image transition edge physical modeling method for exact object shape position determination. Automatic Optical Inspection systems for the high accuracy optical measurements is main application area for designed method. The new method design is based on precise physical analysis of a defined imaging system. Object side telecentric lens, telecentric backlight source and CCD video camera are main parts of the analyzed imaging system. New image transition edge physical model and method for accurate shape position detection within the model are derived by geometrical and Fourier optics imaging system analysis. Possible influences of the model parameters changes to the accuracy of shape position detection are studied precisely. A new modeling function suitable for implementation in a new optimal approximation method is derived from the physical transition edge model. The modeling function optimal approximation method is implemented in to a Tester2D measuring system and verified by length etalon measurements. The Tester2D measuring system was successfully accredited for dimensions measurement in range with accuracy up to . Documentation of results of the accreditation process with the record of obtained results from measurement system in scope of preformed interlaboratory comparison tests are appended to the doctoral thesis.

Profilometry Measurements Of Magnetic Plates Mounted On Rotors
Mach, Radoslav
Presented project deals with optical profilometric analysis of magnetic plates positionwithin the rotors surface. The focus of this work is to determine whether measuring by laserprofilometry scanning of the surface is suitable for such an issue. Main problem is occasionalinaccurate positioning of magnetic plates which might occur in gluing of the plates duringmanufacturing process. This could lead to inhomogeneous magnetic field causing dysfunctionalproperties of the device. Results demonstrate that profilometric measurements are sufficient optionfor solving the problem, nevertheless there is need for special equipped profilometric system tomeasure and evaluate data properly.
