Segmentation of arterial wall in high resolution retinal images
Polachová, Natálie ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
This thesis focuses on automatic segmentation of retinal arterial walls in images acquired using adaptive optics. Adaptive optics is a non-invasive imaging method that provides high lateral resolution and allows detailed observation of retinal microstructures, including arterial walls. This technology is crucial for early diagnosis of serious diseases such as arterial hypertension and diabetic retinopathy. The main objective of this work was to detect the arterial lumen and segment its walls. Morphological and filtration techniques were used for lumen detection. For arterial wall segmentation, brightness profiles along the detected lumen were analyzed and active contour and spline methods were used. The results show that the active contour segmentation method improves the accuracy of arterial wall detection, especially in high-contrast regions. This thesis summarizes the findings and proposes improvements in the detection of the inner side of the arterial wall, which reduces the segmentation success rate in this work.

Design of adaptive mirror for high power laser applications
Kroutil, Tomáš ; Zatočilová, Aneta (referee) ; Koutný, Daniel (advisor)
Bachelor thesis deals with design and production of the prototype of adaptive mirror for high power lasers. Deformation of mirror is possible by a set of tensile elements and air pressure. The deformation of reflective surface is in tenths of millimeters. The research part is devoted to laser technology with adaptive optics. The design part contains several design variants and optimal solution, which was chosen for realization. Real deformation of reflective surface was evaluated by 3D scanner.
