Perovskite-based optical sensor
Frkáň, Lukáš ; Jandová, Kristýna (referee) ; Novák, Vítězslav (advisor)
The aim of this Master´s thesis is to frame the concept of perovskite-based materials, provide basic information about perovskite-based materials and scrutinize their potential in terms of optical sensors manufacturing. The thesis also deals with monitoring of the sample in terms of long-term stability. The analysis of measured characteristics and their properties is included in this semester thesis as well, along with the methodology of testing and evaluating of the results.

Research and Development of 2D/3D Deformable Structures LTCC for Optoelectronic Applications
Somer, Jakub ; Pietriková,, Alena (referee) ; Husák, Miroslav (referee) ; Szendiuch, Ivan (advisor)
The doctoral thesis is focused on the research, development and production of deformation elements produced by LTCC technology for use in optoelectronic applications. A study of technological processes is carried out, with the emphasis on achieving accurate and reproducible mechanical component manufacturing so that these can be used on standard LTCC substrates in the commercial sphere. Therefore, available standard thick-film materials are used. The work also involves testing the suitability of the use of standard LTCC materials for selected sensory applications in which fiber optics are used to confirm the usefulness of the results achieved in practice. The dissertable core of the work is research and development of a technology using new principles and possibilities hidden in the mechanical parameters of LTCC structures, which are designed and used for the realization of deformation elements. The work also involves testing the suitability of the use of standard LTCC materials for selected sensory applications in which fiber optics are used to confirm the usefulness of the results achieved in practice.

Optical Fibers Forming For Optical Sensors
Research
Jelínek, Michal
We present development of new methods and techniques of the splicing and shaping optical fibers with focusing to development new sensors. We developed new techniques of splicing for standard Single Mode (SM) and Multimode (MM) optical fibers and optical fibers with different diameters in the wavelength range from 532 to 1550 nm. Together with development these techniques we prepared other techniques to splicing and shaping special optical fibers like as Polarization-Maintaining (PM) or hollow core Photonic Crystal Fiber (PCF) and theirs cross splicing methods with focus to minimize backreflection and attenuation. Splicing special optical fibers, especially PCF fibers with standard telecommunication and other SM fibers, can be done by light adjustment of our developed techniques.

Mobile robot sensor system
Juhás, Miloš ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
In this Bachelors thesis is processed the basic theoretical knowledge needed to design sensory system for a small mobile robot and the sensory system itself is designed. Thesis describes the working principle of tactile, optoelectonic and ultrasound sensors, their basic features, advantages and disadvantages. Next there are processed known prospects of sensors electrical schemes for line following and obstacle detection sensors and commercialy available solutions are briefly described. In the second part there is, based on introduced principles, experimental schemes and measurements, the sensory system itself designed, which is capable of advanced detection abilities and microprocessor conducted data processing. The design is focused on power usage optimisation, control software efficiency and extended universality of designed system. Part of the thesis are libraries of functions required for simple control and sensory system application. In the epilogue there are listed and evaluated the testing results and measured parameters of designed system.
