Web13. jún 2014 · A robust model for simulating speckle pattern evolution in optical coherence tomography (OCT) depending on the OCT system parameters and tissue deformation is reported. The model is based on application of close to reality procedures used in spectral-domain OCT scanners. WebA speckle pattern is a spatial high-frequency random intensity pattern of energy produced by the mutual interference of a large number of coherent wavefronts. When light is transmitted in a multimode optical fiber, many modes of light exist with different optical phases. When observed at the end of the fiber, a laser speckle pattern exists as ...
