| Abstract: | Numerical reconstruction is a key procedure of digital holography.Classical reconstruciton algorithms are characterized by the twin images,superimposition of in-focus and out-of-focus object,and so on.Application of the new compressive sensing theory to sparsity reconstruction of digital inline holography is investigated.Based on the linear operator of diffraction model,the algorithm for the reconstruction of digital inline holography using compressive sensing is derived.Holograms of particle field from bot... |
