Abstract

We describe a novel method that estimates the Doppler angle and flow velocity. This method uses en-face OCT imaging and border detection in order to evaluate the Doppler angle. C-scan images are collected at different depths for two particular orientations of the pipe. We evaluate the possible sources of errors in an experiment of intralipid flow at different speeds through a 1.3 mm pipe. Using a FFT signal analyser, we collected at different depths, the Doppler frequency shift due to the axial motion of flow. Knowing the Doppler frequency shift, the flow velocity can be estimated using the Doppler angle achieved applying the method introduced here.
