Abstract

In order to improve the effect of twin-image elimination in in-line holography, a novel iterative algorithm was proposed. The off-axis hologram is added to the iterative process as a part of the constraints through interference and inverse interference processes.The full frequency spectrum could be retrieved iteratively after taking full advantage of the spacebandwidth production of the detector. As one form of in-line holography, the theoretical resolution is diffraction limitation. Numerical simulations were carried out to validate the proposed method. The quality of the reconstructed image is improved remarkably compared to traditional in-line or off-axis digital holography.
