The thesis deals with LSCI (Laser Speckle Contrast Imaging), an optical method utilizing laser speckle contrast for the estimation of blood flow changes. LSCI is non-invasive and technically not demanding approach, capabilities of which have not yet been fully exploited. The literature review part contains detailed description of the operating principle, imaging techniques, potential for medical applications with considering the limiting factors. The main aim of the thesis is to design and construct a complete LSCI system including appropriate phantoms able to simulate blood flow through the tissue. Imaging algorithms for the obtained data evaluation were implemented in Matlab® development enviroment. Finally, the created system was tested using different acquisition parameters as well as varying the image processing schemes. The resulting qualitative flow images were subsequently discussed and confronted with the theoretical assumptions.
