Coherence-gate assisted three-dimensional imaging by holographic microscope
Maršíková, Barbora ; Heintzmann, Rainer (oponent) ; Chmelík, Radim (vedoucí práce)
This master thesis covers the primary research on the influence of spatially incoherent illumination on the axial localization of small details in a three-dimensional sample. The imaging is done by the coherence-controlled holographic microscope (CCHM). The necessary theory of imaging and scattering is summarized in the theoretical part. The fundamental principle as well as the actual setup of the microscope is described in detail and a mechanical adaptation is designed for the use of condenser optics with high numerical aperture and low aberration. For the experimental part, a model sample has been prepared and measured. The relationship between the spatial incoherence of illumination and the axial localization is demonstrated on simulations and verified experimentally using the model sample. The experiments prove the basic idea of the theory. In the end, some improvements are suggested for the future research on this topic.
