Measurement of Spectral Characteristics of Fluorescent Voltage-Sensitive Dyes
Pavlík, Dušan ; Čmiel, Vratislav (referee) ; Provazník, Ivo (advisor)
This bachelor thesis deals with optical measurement of substances properties in practical service of absorption and fluorescent spectroscopy. The work specifies the principle of fluorescence, which has direct association with spectral characteristics measurement of so-called voltage-sensitive dyes (in this instance di-4-ANEPPS). This dye is used for contactless (optical) imaging of organisms electric activity in practical service of its voltage dependent spectral shift after binding itself on cell membrane. However, the right application of this fluorescent dye is dependent on too many factors – one of them, discussed and measured in this work, is di-4-ANEPPS spectral dependency on its immediate environment.

Ultrasonic blood flow meter
Pavlík, Dušan ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
This thesis deals with ultrasound blood flow meter design with emphasis on practical implementation of such device. This medical device is used in ultrasound diagnostic, especially for measuring direction and velocity of blood flow in superficial vessels. This thesis contains consecutive design including description of individual function blocks. Documents for making double-sided printed circuit are included as well.
