Abstract
We propose a viewing-angle-enhanced integral imaging (InI) 3D display using two tilted folding mirrors. The tilted folding mirror generates a corresponding additional virtual tilted micro lens array (MLA) adjacent to the real MLA, which is similar to a curved MLA structure. The two virtual tilted MLAs emit tilted light beams with larger tilt angles than conventional InI, which results in an enhanced viewing angle. A modified elemental image synthesis algorithm is proposed to match the proposed scheme. Visualization simulation and optical experiment are performed to verify the proposed method.
