Abstract: | Compressive holography applies sparsity priors to data acquired by digital holography to infer a small number of object features or basis vectors from a slightly larger number of discrete measurements. Compressive holography may be applied to reconstruct 3D images from 2D measurements or to reconstruct 2D images from sparse apertures. This paper is a tutorial covering practical compressive holography procedures including field propagation, reference filtering, and inverse problems in compressive holography. We present as examples 3D tomography from a 2D hologram, 2D image reconstruction from a sparse aperture and diffuse object estimation from diverse speckle realizations. | ||||||||||||||||||||||||||||||||||||||||||||||||||
