What is it about?
An holographic microscopy setup using two illumination beams is proposed to image blood microcirculation in preclinical models. Greedy algorithm reconstruction of the two resulting holograms leads to a 3D reconstruction of the sample over time.

Why is it important?
We proposed a technique that combines digital holography, dual illumination of the sample and reconstruction with a greedy algorithm to obtain 4D images of blood microcirculation in a living zebrafish embryo.
