We propose the use of synchronously moving micro-optics (lenslet arrays) for image pickup and display in three-dimensional integral imaging to overcome the upper resolution limit imposed by the Nyquist sampling theorem. With the proposed technique, we show experimentally that the viewing resolution can be improved without reducing the three-dimensional viewing aspect of the reconstructed image. Recording elemental images with enough resolution is also an important factor in determining the viewing resolution of the reconstructed image. We investigate the use of an optically addressed spatial light modulator, because it provides potentially better image resolution than the conventional CCD and liquid crystal display pair. We present experimental results using a liquid crystal light valve. A two-step integral imaging system to obtain three-dimensional orthoscopic real images is also presented.
