Abstract
AbstractIn this paper, we propose a depth‐enhanced integral imaging display based on bifocal lens array. The bifocal lens array consists of a small lens array with plano‐convex circular lens units and a large lens array with square lens units. The proposed display device generates two central depth planes and stitches two reconstructed 3‐D images in depth, which largely improves the depth of field. The experimental results indicate that the proposed structure reconstructed 3‐D image with the depth of field as large as 150.8 mm, which is double of conventional integral imaging display.
