Compressive sensing holographic microscopy for imaging of sparse moving objects in 3D

Compressive sensing combined with digital holographic microscopy is well adapted to image in 3D and in time, small scattering objects moving within a larger motionless object. This situation corresponds to red blood cells (RBCs) circulating in the vascular system of a zebrafish larva (Danio rerio). RBCs positions are imaged in 3D from a single hologram, while the RBCs trajectories, i.e. the perfused blood vessels, are imaged from a sequence of holograms..
