N2 - A new approach for resolution enhancement of integral imaging three-dimensional display using multi-directional elemental images is proposed. The proposed method uses a special lens made by nine pieces of Fresnel lens which are collected from different parts of the same lens. This composite lens is placed in front of the lens array such that it generates nine sets of directional elemental images. These elemental images are overlapped on the lens array and produce nine point light sources per each of elemental lens at different positions in the focal plane of the lens array. Nine sets of elemental images are projected by a high speed deformable mirror device and are tilted by two-dimensional scanning mirror maintaining the time-multiplexing sequence for nine pieces of the composite lens. In this method, the concentration of the point light sources in the focal plane of the lens array is nine-times higher i.e. the distance between two adjacent point light sources is three-times smaller than the conventional integral imaging display, hence the resolution of three-dimensional image is enhanced.
