Visualization of vocal cords movement
Kutálek, Libor ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
The aim of this work is to clarify the function of the vocal cords and get familiarized with their investigative methods. In this work we find possible solutions to the peripheral device to illuminate the rapidly vibrating vocal cords using an LED that is less energy exacting than conventional halogen lamps. Then there are solved the problems of processing, signal filtering and finding the natural frequency of vibration of the vocal cords.

The main object of these work is show how does vocal organism of a man work and how can we examine it. We are familiarized with methods for objectification of investigation glottis by the help of modern videotechnology. In this work we could found draft of stroboscopic source of light, whitch would be used for investigation glottis in videolaryngosrtoboscopy. In the following part of this work is shown experimental examination functional section, whitch would me used for investigation in practice.
