Abstract
In this paper, we propose a holographic zoom system without the undesirable light caused by zero-order diffraction beam and high-order reconstructed images. By loading a divergent spherical wave, the focus planes of the reconstructed image and the zero-order diffraction beam induced by the liquid crystal on silicon (LCoS) can be separated. By controlling the focal lengths of the liquid lens used in the system and the encoded divergent spherical wave on the LCoS, we can change the magnification of the reconstructed image very quickly, while the system does not have undesirable light and the output plane of the system keeps stationary.
