Paper Abstract

We have developed a novel optical Hilbert transformation for phase-resolved optical Doppler tomographic imaging. Using a resonant scanner in the reference arm of the interferometer and the axial scanning speed of 4 kHz, the frame rate can be as high as 10 Hz for both structural and Doppler blood flow imaging 400 axial scans. The system has high sensitivity for measuring the Doppler frequency shift due to moving red blood cells. Real time images of in vivo blood flow in human skin using this interferometer are presented.
