COHERENCE-CONTROLLED HOLOGRAPHIC MICROSCOPY IN DIFFUSE MEDIA
Lošťák, Martin ; Komrska, Jiří (referee) ; Šerý, Mojmír (referee) ; Chmelík, Radim (advisor)
This thesis deals with imaging through diffuse media in coherence-controlled holographic microscope (CCHM) developed in IPE FME BUT. The mutual coherence function as well as the signal dependence on the lateral mutual shift between both arms of the CCHM are calculated. Both functions are related to each other. The latter dependence is measured experimentally. A principle of imaging with CCHM through diffuse media with both ballistic and diffuse light is explained by a simple geometrical model. This model is then verified experimentally by imaging a sample through diffuse medium. The point spread function (PSF) of CCHM for imaging through diffuse media is then calculated. Results of PSF calculation are proved experimentally.
Amplitude and phase objects observation through scattering media by means of coherence-controlled holographic microscope
Effenberger, Adam ; Lošťák, Martin (referee) ; Kollárová, Věra (advisor)
This diploma thesis deals with phase and amplitude objects observation through scattering media by means of a coherence-controlled holographic microscope (CCHM). A brief history of development and construction of the microscope, its advantages compared to the classical light microscopy and hologram processing are described. Quantitative phase imaging through scattering media by means of ballistic as well as diffuse light is verificated in the experimental part. A comparison of an image obtained through a scattering layer by means of CCHM and a classical microscopy in the light field is demonstrated.
