Abstract
Tabletop autostereoscopic displays have the advantage of displaying realistic three-dimensional (3D) content. In particular, the Integral imaging (InIm) method is superior in tabletop displays, as it is possible to make the system small using microlens arrays (MLA). Off-the-shelf MLAs have a small field of view (FOV) and are unsuitable for tabletop displays where the half viewing angle is typically around 45 degrees. The MLA for tabletop display also needs to have uniform angular resolution and low crosstalk to display 3D content. In this paper, we designed a new MLA with a multilayer structure and a reversed lens shape. This lens array has a wide viewing angle of −58 degrees to +58 degrees, with uniform angular resolution and low crosstalk of less than 0.2. We implemented a tabletop display using our MLA and verified its properties experimentally. The misallocation error of the elemental image is experimentally measured and compensated for as well.
