Methodology of Dictyostelium discoideum imaging with the transmission digital holographic microscope
Křížová, Aneta ; Ježek, Jan (referee) ; Uhlířová, Hana (advisor)
The task of this bachelor’s thesis was to image Dictyostelium discoideum with a transmission digital holographic microscope and compare this imaging with a commonly used microscopy technique. This bachelor's thesis is structured into a theoretical part and an experimental part. The theoretical part describes the setting of the transmission digital holographic microscope, basic operation and physical principles of imaging with this microscope. Further the process of image reconstruction and numerical process of phase reconstruction is illustrated. At the end of this part, basic biological characteristics of observed cells of Dictyostelium discoideum are introduced. The experimental part describes the cultivation and preparation of Dictyostelium discoideum for the observations, and further the process of performed experiments. The cells of Dictyostelium discoideum have been imaged in couple experiments by a method of the classical phase contrast. By the transmission digital holographic microscope the cells of Dictyostelium discoideum have been imaged in two mediums. Images captured by the transmission digital holographic microscope were processed by a method of Dynamic phase differences and analysed.
