Simulation tools for light-field displays based on a micro-lens array

A group of tools has been developed to analyze the display performance of light-field displays based on a micro-lens array. The simulation tools are based on the principle of Snell's Law and the characteristic of human visual system, in which the optical aberrations of lens arrays and the focus of eyes have also been taken into account. Some important issues in light-field displays can be shown clearly before the fabrication, such as perspective views, view zones, crosstalk, color moire patterns, and also the depth information in light-field near-eye displays. Therefore, the developed tools can provide a useful approach to verify the improvement of new techniques and also give a reference of the final performance for a system set-up with optimal specification. To our best of knowledge, the developed tools is the first approach to analyze the performance of 3D displays considering the optical aberrations and the characteristic of human visual system.
