Optical link intended for indoor network
 Hrbáčková, Petra ; Vlček, Čestmír (referee) ; Wilfert, Otakar (advisor)
This thesis deals with the structure of the optical wireless link intended for indoor applications. Optical transmitters and optical receivers as the basic elements of optical links and their characteristics and parameters are described. The characteristics of lenses used in the transmitter and receiver are presented. The special chapter is devoted to the directional reflectance properties of surfaces. The last part of the thesis is focused on a specific proposal of the wireless optical links and its power level diagram.

Teaching aids for fibre optics, optical communication and optoelectronics
 Hrbáčková, Petra ; Křivák, Petr (referee) ; Wilfert, Otakar (advisor)
This thesis presents basic characteristics of the optical detectors, transmitters and optical plastic fibres. The basic optoelectronic transfer, principle of transmission, information transfer by the plastic fibre and principle of receiving are described. The practical aspect of the thesis serves as a basic illustration of the logic analogue signal transfer through the fibers by optoelectronics methods.

Application versatile module LabJack\hindex{TM} in education of physics
 PŘIBYL, Vojtěch
Theme of this thesis is using of universal module LabJack U3-HVTM as support for physics lessons. This thesis describes the universal module LabJack U3-HVTM and evaluation method of measured value on the computer screen using software eSimLab. To all physical tasks is described path of signal with measured string from developed sensor until evaluation of signal in the computer. In the thesis is specifically described a function of developed sensors of physical quantities, there are subscribed diagrams including PCB and parts list. The thesis is including designed physical tasks for monitoring of atmospheric pressure, temperature, wind direction, sunshine duration and the role of measurement of the signal on the optical transmitter using the developed sensors and universal module LabJack U3-HVTM.
