The improvement of holographic reconstruction images using a common diffuser film

摘要

In General, reconstructed holographic images are not easily distinguishable due to the problem of overlapping between strong zeroth-order diffraction beam and relatively weaker other higher order diffraction light. In this paper, we proposed a idea that the reconstructed holographic image is substantially improved to be clear and distinguishable, i.e., suppressing the zeroth-order diffraction component using only a sheet of diffuser film. The proposed method is also demonstrated with a series of experiments.
