Design of the telescope spectrograph for distant object analysis
Drobil, Tomáš ; Pořízka, Pavel (referee) ; Novotný, Jan (advisor)
Meteor spectra obtained from orbit include many spectral lines in the ultraviolet region, which is mostly absorbed by the atmosphere and thus cannot be observed from ground stations. This bachelor thesis focuses on the design of a spectrograph, placed in a 2U CubeSat, suitable for meteor observation and its spectral analysis in the range from the ultraviolet to near-infrared region. The design includes choice of a suitable camera. Based on the required parameters, several designs have been created, and the process is summarized in the last chapter. The research study of telescopes combined with spectrometers used for meteor observations is also included.

System for maintaining the sharpness of the image for the light microscope
Dokulil, Jakub ; Bouchal, Petr (referee) ; Dostál, Zbyněk (advisor)
Live imaging je klíčovým nástrojem pro moderní biologické objevy. Bez techniky pro udržení ostrosti obrazu je však stěží proveditelný. V této práci předkládám aplikaci optických vírů pro axiální lokalizaci vzorku tak, aby se obraz mikroskopu udržoval zaostřený. Experimentalní sestava pro axiální lokalizaci z předchozích experimentů byla přepracována, aby se rapidně zmenšily její zástavbové rozměry, tak, aby jí bylo možné integrovat jako modul do mikroskopu. Sestava byla následně realizována a byla úspěšně experimentálně otestována. K tomu bylo třeba také navrhnout řídící software. A připravit skript se zpětnou vazbou pro budoucí integraci do mikroskopu.

Design of an active protection system LIDAR for the detection of subsonic missiles
Gedeon, Sebastián ; Vilém, Jan (referee) ; Antoš, Martin (advisor)
The diploma thesis focuses on the design of an Active protection system LiDAR, with emphasis on the research for the operation of these systems and the components of which the system consists. It specifies the basic optomechanical parameters that the designed system must achieve. The thesis introduces a conceptual design of an optical system for ground surveillance and aviation surveillance. LiDAR systems are made of off-axis or Cassegrain telescopes. As a part of this thesis are also designs of an optical illuminating system and a zoom lens for infrared imaging.

Raman assembly for radiation analysis
Stránská, Lenka ; Ježek, Jan (referee) ; Dostál, Zbyněk (advisor)
For Raman spectroscopy is a need to introduce a laser light into an optic fiber and analyze a collected light at the same time. Therefore it was proposed a specialized optical system. This system can also be used to measure other spectroscopy methods such as photoluminescence. In the theoretical part of this theses, was discussed both mentioned methods and their instrumentations. In addition to the Raman spectroscopy, was also shown some special cases of Raman spectroscopy for enhanced measurement of Raman scattering. The problem of weak signal detection and its reading is also discussed in the theoretical part of the thesis. In the practical part of this thesis was discussed the mechanical design of the optical system and the choice of optical elements that are used in the system. Next, is introduced the manufactured system, which design is based on the parameters of the chosen optical elements. The practical part of the thesis ends with an assembly and testing of the proposed system.

Optical design of telecentric F-theta objective
Perháč, Timotej ; Zámečník, Jan (referee) ; Antoš, Martin (advisor)
This thesis deals with optical design of f-theta lens for purposes of precision micromachining using a laser beam. Optical design consists of creating a nominal design according to specifications given by Meopta – optika s.r.o company and a tolerance analysis, which describes manufacturability of given design. Specifications given are most importantly diffraction limited image quality, correction of distortion throughout the field and telecentricity of systém in image space. F-theta lens in this thesis was created using an optical design software called Zemax.

Fiber guided illumination module
Kropáč, Vlastimil ; Kvasnica, Lukáš (referee) ; Dostál, Zbyněk (advisor)
This diploma thesis describes the design of the illumination system for a Coherence--Controlled Holographic Microscope (CCHM). The theoretical part mentions the history of microscopy, the principle of holography and individual types of interference microscopy. To get closer to the topic, individual light sources and an overview of current illumination systems are mentioned. The diploma thesis also describes the procedure of designing a fiber-optic illumination module for microscopy from optical design through design of construction to the last step, which is assembly and testing of the module.

Design of indoor lighting in a trend of Human Centric Lighting
Ruml, Filip ; Baxant, Petr (referee) ; Antoš, Martin (advisor)
The main tasks of the thesis lie in summary of present state in Human Centric Lighting field, in the optical design of luminaire and in practical verification of the proposal. The design is developed in software LightTools and for the verification of functionality the software Dialux EVO is employed. The luminaire is designed primarily with respect to the influence of light on the man and the physiological, psychological and behavioural responses in humans. The thesis is created in cooperation with the company Robe Lighting s.r.o. The proposal of the luminaire corresponds to the current state of knowledge in the area of light influence on humans. The designed luminaire in the trend HCL is distinguished by the high quality of emitted light but also with higher costs of the operation.
