Sing-sensitive one specific velocity mapping of a flow with complex geometry using optical coherence tomography

摘要

The method of sign-sensitive one specific velocity (OSV) mapping of flow with a complex geometry based on the principles of Doppler optical coherence tomography (OCT) is described. Structural and one specific velocity images are obtained using the signal of a scanning interferometer processed in frequency domain. Analog and digital filtering was also applied. Standard structural image is decomposed into three parts: stationary object, positive and negative OSV images. The latter two show equivelocity maps of the flow. The final image is represented as the complexation of the three ones.
