Controlling and Evaluation of Laser Micromanipulation Experiments
Kaňka, Jan ; Jákl, Petr (referee) ; Provazník, Ivo (advisor)
This work is focused on the development of a user friendly software interface using the LabViewTM environment that simplifies running of various experiments using laser micromanipulations and laser microspectroscopy of living microorganisms. Both techniques have been developing very fast for the last decade and belong to the growing group of contact-less and nondestructive techniques for manipulation and diagnostics of individual living microorganisms, cells, or viruses. Within this project we mastered the driving of peripheries, calibration of CCD scene, real-time image processing of the CCD scene, automatic selection of the cell for further laser processing, acquisition and processing of the Raman spectrum from living microorganisms. The final goal of our activity is fully automatic laser-based sorter of living cells depending on their chemical compositions. This work has been elaborated at the Institute of Scientific Instruments of the ASCR, v.v.i. under the supervision of prof. Pavel Zemanek.

Optimization of optical tweezers for multimodal holographic microscope
Vaverka, Jan ; Antoš, Martin (referee) ; Dostál, Zbyněk (advisor)
This bachelor's thesis has described the principle of operation of interference microscopes with closer analysis of multimodal holograpfic microscope (MHM), which has been constructed at the Institut of Physical Engeneering (IPE) of Brno University of Technology. It has also analysed principles of optical trapping and has closely descirebed force effects on the trapped object with characteristic lenght bigger than wavelenght of trapping beam. It has designed optimization of existing optical tweezers module so that the module is connectable to the prototype of MHM, located at IPE. Simulation and optimization of the optical assembly of module have been performed, the mechanical design of module with the drawings has been designed. The module has been entered into production.
