Abstract
In this paper we report that optical inhomogeneity of flowing fluid has influence on Doppler OCT measurement. Additional Doppler signal from scattering steady medium below blood vessels is visible. To investigate this phenomenon, the experiments with different scattering mediums and different well controlled experimental configurations were carried out. Imaging was performed using SOCT instrument with CCD camera, and joint Spectral and Time domain OCT method was used during data analysis.
