Method and apparatus for optical Doppler tomographic imaging of fluid flow velocity in highly scattering media

摘要: Optical Doppler tomography permits imaging of fluid flow velocity in highly scattering media. The system combines velocimetry with high spatial resolution partially coherent optical interferometry to measure at discrete locations. Noninvasive vivo blood dynamics and tissue structures resolutions the order 2 10 microns is achieved biological systems. backscattered interference signals derived from interferometer may be analyzed either through power spectrum determination obtain position each particle sample pixel, or spectral density frequency positions velocities particles a cross-section which corresponds. realized allows noninvasive both microcirculation structure surrounding vessel has significance for biomedical research clinical applications.
