4D compressive sensing holographic imaging of small
moving objects with multiple illuminations
Posted on 2019-10-09 - 16:39
In previous work (Brodoline et al., Opt. Lett. 44, 2827 (2019)), we presented a method based on digital
holography and orthogonal matching pursuit (OMP), which is able to determine the 3D positions of small
objects moving within a larger motionless object. Indeed, if the scattering density is sparse in the direct
3D space, the compressive sensing (CS) algorithms can be used. The method was validated by imaging
red blood cells trajectories in the trunk vascular system of a zebrafish (Danio rerio) larva. We give here
further details on the reconstruction technique and present a more robust version of the algorithm based
on multiple illuminations.
