Microscope and it´s use in engineering practice
 Kopecký, Jiří ; Dostál, Lukáš (referee) ; Veselka, František (advisor)
This work deals with the use of the light microscope in industry and its use within the automatization of the diagnostic method specialized on electrical machines with a sliding contact. The method is called the dust particles method and it is used to determine the loss of the brushes used in the machines. The current method involves a manual evaluation of an acquired data, which demands additional tests and the evaluation itself is very difficult. The objective of this work is to simplify and accelerate the method using the computer analysis. First, the usage of the light microscope, through which the samples are obtained, is showed. The method uses these samples as the input. Then, the principles of the dust particles method are demonstrated and the image analysis using the MATLAB program follows. The guide to the image analysis with the elimination of rising defects using the MATLAB program is available. Then, the volume of the intercepted dust particles is calculated using the MATLAB program. The dust particles were obtained from the LFC 55h brush using the Arsenal LPT 1513 – T light microscope.
