Quantitative measurement of oil droplets using compressive digital holography

Compressive holography is applied to characterize the oil droplet in oil spill experiment. The compressive reconstruction method demonstrates good performance in the real experimental data compared with traditional back-propagation based method. The phase transition curve in simulation illustrates the effects of sparsity of object function on the compressive reconstruction success rate, which indicates the effectiveness of free space propagation as a signal mixer in compressive measurement.
