Paper Abstract

Optical Doppler Tomography (ODT) is a high-resolved and non-invasive biomedical imaging technique, which can obtain tissue structure and blood flow velocity at the same time. A novel phase-resolved ODT method to measure 3-D velocity vector is presented. After inserting the designed narrowband phase plate between the collimator and focusing lens of the sample arm, three independent path length delays are formed. By calculating the Doppler shift and the Doppler bandwidth corresponding to three delays, 3-D velocity vector distribution of the solution inside the glass capillary is obtained. Experiments of polystyrene solution flowing at different velocity are conducted, demonstrating the feasibility of the proposed method for 3-D velocity vector measurement.
