Abstract : This work reports on the feasibility of dynamic imaging using conventional reflectivity-based tomographic images obtained with full-field optical coherence microscopy (FF-OCM). Implementation of speckle variance for flow mapping with an imaging rate of 180 Hz is demonstrated by mapping 20% intralipid flowing into 100-μm-diameter microcapillary tubes at speeds up to ~ 50 mm/s. This constitutes a significant advance in high-resolution, real-time microvasculature mapping, using FF-OCM. The acquisition scheme in FF-OCM is particularly appropriate for en face visualization of the microvasculature, as FF-OCM directly acquires en face tomographic images unlike conventional OCT which usually requires reslicing of a three-dimensional data set to get en face images.
