Automatization of an optical setup for time-resolved spectroscopy
Šimek, Daniel ; Klenovský, Petr (referee) ; Dvořák, Petr (advisor)
Time-resolved spectroscopy is a modern method enabling the analysis of the dynamics of quantum luminescence transitions. This method uses ultra-fast light pulses to study materials, which makes it possible to observe the time evolution of luminescence quenching and thus provides additional information for static absorption and emission spectroscopy. This diploma thesis deals with the automation of the optical setup used in the Optical and Plasmonic Laboratory at Ceitec Nano for performing time-resolved spectroscopy. As part of the work, an application was created enabling communication with 13 devices used in the laboratory. The application automates already performed measurements, and in addition enables the scanning of samples, which was not possible due to time constraints due to the manual control of the stage movement. At the end of the work, test measurements are performed, with a discussion of their effectiveness and time savings for the user.

CAD design of the Walther PPS M2 laser sight housing
Macků, Veronika ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
The aim of this thesis is to create a housing for a laser-sight for a Walther PPS M2 pistol with the aid of reverse engineering methods. The first part is a research about laser-sights. The second part contains contemplation about the problem, mainly the restrictions brought on by the design of the Walther pistol and of the energy source of laser-sight Streamlight TLR-6, as well as the chosen production method of the housing, which is 3D printing. The main part describes the acquirement of input data via scanning the body of the Walther pistol and the housing of TLR-6, the making of the CAD design of the housing, the printing of a prototype with a 3D printer and the consequent correction of the CAD model on the basis of analysis of the prototype.

Using of modern software support in the projection practice of process engineer
Zajíc, Jonáš ; Babička Fialová, Dominika (referee) ; Jegla, Zdeněk (advisor)
The presented MSc. thesis is focused on the introduction and application of PDMS software in the process piping designing area. The introduction to the employing of the PDMS software is elaborated in the first part of the thesis as practical user manual of this software followed by the benefits of this software as a recognized supportive design program are consequently illustrated on partial solved cases from common design practice. The particular benefit of deploying PDMS in design practice is demonstrated in the thesis by economic evaluation of two selected solved industrial projection cases where design optimization of process piping system is solved with the support of this software system. Introduction of new ones broadening possibilities and current trends in the supportive design software systems, specifically using the scanner and supporting Everything3D are also presented as part of the thesis on a concrete example of the reconstruction of the boiler room.

Design of a 3D scanner for educational purposes
Paprsek, Adam ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
The aim of the submitted semestral project is research of 3D scanning object methods. The 3D scans utilization and types of these scans have been mentioned in the first chapter. The scanners are grouped into two basic methods – contact and contactless. The second chapter is dedicated to 3D model measurement principles, which are described in detail in four sub-chapters. In the following chapter is described design with complete realization 3D scanner with the implementation of the application for its controlling. Last part of the thesis concerns the 3D model editing and method evaluating.

Digitization of 2D objects in museum collections
Wenzl, Jonáš ; Vaněk, Jiří (advisor) ; Stočes, Michal (referee)
The thesis focuses on the analysis of digitization of two-dimensional objects and determination of methods applied to the collection in the Krkonoše Museum in Vrchlabí. The first part introduces and explains the theoretical basis. The second part contains an analysis of the digitization project in the Krkonoše Museum, compilation of methods from checking the object to its saving to data storage. Using the analysis, the main benefits and risks of digitization are ascertained. In conclusion, the digitization project of the Krkonoše Museum is assessed with the emphasis on the practical experience in the digitization of two dimensional objects, the possibilities of digitized collections and suggestions for further implementation. The solution provides
a secure way of creating digital copies of objects of cultural and historical value, their archiving and future use of the data. The findings could be beneficial for other digitization projects.

Design of Portable 3D Scanner
Štigler, Jaroslav ; Rubínová, Dana (referee) ; Sovják, Richard (advisor)
The topic of this bachelor‘s thesis is design of handheld 3D scanner. This scanner belongs in the higher price category. This thesis deals with problems like long working time, watching monitor during scanning, versatility and safety measures from mechanical damage. Ergonomic solution is also very important. This design is based on a simple and functional shaping. Shaping and color solution corresponds with its use in industry. This scanner also can be used in other fields (for example: medical sector, design, archeology, etc.).
