Non-elektricity Quantities Fiber Optic Sensor
Mytyska, Kamil ; Škorpil, Vladislav (referee) ; Filka, Miloslav (advisor)
This diploma thesis deals with an analysis of the method of propagation of optical fiber by two polarization planes. The method of light propagation is mathematically described using Jones and Stokes vectors. The first part describes wave theory of light divided by Fresnel wave theory, polarization ellipse, degenerate polarization states, parameters of polarization ellipse, Poincaré sphere and degenerated states on Poincaré sphere. Then follows Stokes and Jones polarization parameters, their vectors and Mueller matrix. In addition this paper illustrates the principle of the temperature sensor which is carried out with the help of the polarimeter and its computer program. The following is design of temperature sensor, which is composed of polarizer, photodiode, light output meter and digital multimeter. Another part of the thesis shows the measured values using the current measurement solution using polarimeter and proposed photodiode sensor. At the end of the thesis there is a comparison of the measured values for the three different temperatures that were applied to the optical fiber.

Integration of services in industrial Ethernet networks
Mytyska, Kamil ; Horváth, Tomáš (referee) ; Filka, Miloslav (advisor)
This bachelor thesis deals with industrial Ethernet. Industrial Ethernet refers to the usage of standard Ethernet protocols using rugged connectors and heat-resistant switches in industrial automation and process control. Components used in industrial environments must be resistant to high temperatures, dust, humidity and vibration. The usage of optical fibers in industrial environment reduces the problems of electrical noise and provides electrical isolation to prevent equipment damage. The first part describes the physical implementation of Industrial Ethernet, the physical implementation of other components, Ethernet system features real-time, overview of standards and usage of virtual networks. The work is processed with solutions integrating multiple disparate services in one industrial Ethernet network using VLAN. This is processed by using of simulation program Packet Tracer and then the solution is processed in real network connection with three borrowed industrial switches Moxa, B&B Electronics and Ruggedcom. Further there is processed operation during the communication between devices using Wireshark which describes the TCP connection, sending an HTTP packet and a separate data transfer. As the last part there is mentioned evaluation of five industrial switches from companies B&B Electronics, Cisco, Moxa, N-Tron and Ruggedcom.
