Control of house heating
Hnyk, Marek ; Šandera, Josef (referee) ; Šteffan, Pavel (advisor)
The aim of the final thesis is a proposal and implementation of a system which would enable a heating control on the basis of data gathered by monitoring of particular rooms inside a building. In particular, it is focused on water measurement within the heating system, TUV (non-potable hot water) and the temperature within the space of residential rooms. The system headquarters must enable an automated saving of the measured data. Selected temperature figures will be made accessible by a web interface and continuously saved on the web server.

Control and regulation of the temperature of the drug transport box
Maťašová, Daniela ; Králík, Martin (referee) ; Sekora, Jiří (advisor)
This bachelor thesis deals with the solution of drug transport in a transport box over longer distances. The work also deals with sensors for temperature measurement and methods of its control and regulation. The essence is the design, implementation and verification of the functionality of the transport device, which allows the display of continuous information about the state of the temperature inside the transport box. Temperature control is powered from the car’s on-board network and temperature sensing is powered independently. The transport device allows the setting of the limit temperature up to 35 °C, while exceeding it is indicated by an acoustic and visual alarm. The transport box, which is the result of the work, allows the transport of drugs, and ultimately meets all the requirements of the assignment.

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.

Design of optical fiber temperature sensor for detection of defense perimeter
Zámečník, Ondřej ; Grenar, David (referee) ; Filka, Miloslav (advisor)
This diploma thesis deals with the issue of measuring the ambient temperature using a~single-mode optical fiber used as a temperature sensor. The thesis describes the basic knowledge about polarized light, its propagation in optical fiber and describes special fibers that preserve polarization. It also deals with the representation of polarization states on a Poincaré sphere and the use of Stokes and Jones vectors. In the practical part, several selected methods of optical signal supply to the temperature sensor are measured. Subsequently, the suitability of the given methods is evaluated from the measured results and the courses are compared with the records measured from real routes. This thesis aims to select a suitable connection of a temperature sensor for a long route of optical fiber and verify its functionality.

Birefringence Influence on Polarization Changes and Frequency on Optical Fiber Sensors
Panascí, Marco ; Grenar, David (referee) ; Filka, Miloslav (advisor)
This bachelor thesis deals with birefringence influence on polarization changes and frequency on optical fiber sensors. The objective of the thesis is to design and implement a set of measurements that analyze these effects. The theoretical part deals with analyzing the polarization-maintaning fiber, the polarization of the light, and the sensory optical fibers, with some research. The practical part deals with design of the workplace, control measurement and sensor response at different temperatures. After the practical part there is a discussion over the measured values. It was found that this sensory optical fiber responds to a change in the ambient temperature of the optical fiber. The main result is that the wavelength varies with temperature.

Optical Fiber Output Power Temperature Sensor Measuring Optimization
Koláčková, Aneta ; Grenar, David (referee) ; Filka, Miloslav (advisor)
This bachelor thesis deals with the issue of measuring optic power on the output of single mode fiber, used like temperature sensor, using birefringent. Thesis describes the basic knowledge about measuring power, standards and function of optical power meters. It also deals with polarization and representation polarization states using the Poincare sphere. In the practical portion is measured optic power on the output of the temperature sensor with a photodiod and after that is verifed by a polarimeter. The aim of this thesis is miniaturization of ending device for measuring intensity of light, that means replacing expensive and large polarimeter by cheap and small photodiod.
