摘要：

We propose and present TDOCT (Transversal Doppler Optical Coherence Tomography), a novel method for measurement of particle flow velocity and direction. A quadrant detector can be employed to enable separate detection of light scattered in four different angles. Transversal flow will induce different Doppler shifts in the four interferometer signals, and suitable processing of the spectra or phase changes can be used to determine the amplitude and direction of the transversal flow component.
