Abstract: An optical coherence tomography imaging system includes a Fourier domain optical coherence tomography sensor system, a signal processing system configured to communicate with the Fourier domain optical coherence tomography sensor system to receive detection signals therefrom and to provide imaging signals, and an image display system configured to communicate with the signal processing system to receive the imaging signals. The signal processing system includes a parallel processor configured to calculate structure information and Doppler information from the detection signals in real time such that the imaging signals provide a real time display of combined structure and flow of an object under observation.
