Abstract
We study the optimum design of traditional integral imaging (InI) display system based on an improved view analysis. Human eyes are fully modeled and aberration of lens array is considered. We show that aperture of the elemental lens should be small enough (i.e. F-number>1.7) to prevent the optics aberration decreasing the display performance. Combining with the requirements on an InI system for reconstructing three-dimensional images with a continuous pattern, parallax, and no gap, we introduce an optimum design method aiming to enlarge the depth of focus. The feasibility of the proposed design method is demonstrated with numerical simulation. To the best of our knowledge, this is the first time that the effects of both aperture and aberration on InI performance have been quantitatively analyzed.
