Abstract

We demonstrate a novel decorrelation-based localized transverse flow measurement using a line-field OCT system. The lateral resolution along the line illumination direction is controlled by digitally altering the aperture size and provides a contrast only depends on the speed and resolution along that direction in the decorrelation function. The results from a capillary phantom experiment are highly correlated with the subaperture-based Doppler OCT ground truth.
