Abstract

Based on the existed ways of 2-D reconstructed images by spatial light modulator (SLM), the methods to enhance the reconstructed quality of 3-D images are investigated in this paper. Based on the diffraction theory, the effects of a lattice SLM with a limited fill factor on the reconstructed images are analyzed. Through adding the phase of the convergent spherical wave, the two focused planes of reconstructed images and the multi-order beams caused by the lattice structure of the SLM can be separated spatially. Therefore, the spatial filter is used to eliminate the influences of higher-orders diffraction beams and zero-order light of reconstructed images, respectively. A holographic optoelectronic display system based on liquid crystal spatial light modulator (LC-SLM) is set up to demonstrate this method.
