Abstract

Colour Doppler optical coherence tomography (CDOCT) is important for two-dimensional, high-spatial-resolution tomographic velocity mapping of blood in living tissue. CDOCT is based on optical interference in a scanning Michelson interferometer. A novel detection scheme, phase-locked loop (PLL) has the ability to establish and maintain phase-lock to the interferogram's periodic signal over a wide range of frequency and amplitude variations. Only the values of frequency and reflectivity must be stored on a computer representing a massive reduction in stored data to the conventional approach. The CDOCT system is implemented in bulk optics to test the detection scheme.
