N2 - The possibility of measuring a full Doppler flow depth profile in parallel by use of frequency-domain optical coherence tomography is demonstrated. The method is based on a local phase analysis of the backscattered signal and allows for imaging of bidirectional Doppler flow. The Doppler frequency limit is 5 kHz for the presented measurements and is set by half of the frame rate of the CCD detector array. We measured the flow of 0.3-μm microspheres suspended in distilled water at controlled flow rates and in vitro human blood flow through a 200-μm capillary with a real-time color-encoded Doppler tomogram rate of 2-3/s.
