Optimization of speckle patterns in ghost imaging via sparse constraints by mutual coherence minimization

Year: 2015

Type: article

Abstract: In this Letter the problem of optimization of speckle patterns in a ghost imaging (GI) system is addressed.The mutual coherence between the measuring matrix and the sparsifying dictionary matrix is minimized to obtain the required speckle patterns.Simulation and experimental results are presented, both showing that the quality of the reconstructed results obtained with the optimized speckle patterns is much improved in comparison with that obtained with the general unoptimized ones.We expect this method can be used to design GI systems with high performance.
