Integral imaging is a true, three-dimensional (3D) display technology that captures and reconstructs 3D scenes using two-dimensional (2D) micro-lens arrays. The manufacturing technique of micro-lens arrays is complicated and expensive, thus limiting the application of the technology. An imitating micro-lens array for integral imaging is presented in this letter. Imitating micro-lens array is composed of a cheap lenticular lens and a parallax barrier. The relationship of the parameters of the imitating micro-lens array is analyzed and the parameter formulae are deduced. The arrangement of pixels under a cell of the imitating micro-lens array is presented. The imitating micro-lens array is simulated using ASAP software, and the results prove that the designed imitating micro-lens array is effective. A 3D scene is reconstructed on a 3D display that consists of the imitating micro-lens array and a 17-inch flat panel display.
