Abstract

We present multimodal wide-field optical interferometric microscopy techniques for label-free 3-D imaging of live cells during fast flow. Using cell micro-manipulation approaches, multiple cells are trapped and rapidity rotated, while acquired using optical interferometry. The interferometric projections are rapidly processed into the 3-D refractive-index profile of the cells. The potential of these new techniques is for label-free image analysis and sorting of cells, to substitute current cell sorting devices which are based on external labeling that eventually damages the cell sample. We show possible applications to in-vitro fertilization and cancer diagnosis.
