The trade-off between the aliasing in integral imaging (II) and the level of interference among adjacent elemental images is mathematically studied in this paper. It is then shown that the multiple-access techniques successfully used in communication systems, e.g. frequency-division multiple access (FDMA), can be invoked to ease the trade-off. Implementation of spatial FDMA technique in three-dimensional II is discussed together with its non-idealities and limitations. Elemental images of three toy cars and their corresponding three-dimensional image are finally provided to demonstrate the superiority of the here-proposed spatial FDMA technique.
