Abstract
The measurement of blood-plasma velocity distributions with high spatial and temporal resolution in vivo is important for the investigation of embryonic heart at its early stage development. Optical Coherence Tomography is a non-invasive imaging modality with high resolution (5 to 20μm) that can provide flow velocity information by calculating the Doppler frequency shift. In this paper, a high speed spectral optical coherence tomography system was demonstrated. An achievable scanning speed of 92k line/sec has been reached by using an ultra-high speed linear array CCD camera. The measurable flow velocity range is [-24,24]mm/s using this system. Early stage Chicken embryo heart blood flow was measured in vivo.
