Paper Abstract

An afocal lens array is proposed to form three-dimensional (3D) images. The array, which is composed of many afocal optical units, can form an image whose depth position is dependent on the angular magnification of the unit. The point of an image formed by the whole array differs from that where an image is formed by an afocal unit, except in the case that the angular magnification is 1.0. Especially, when the angular magnification has a negative value, an optical image has a negative longitudinal magnification, i.e., a 3D image with inverted depth. When used for integral imaging, the array can control the depth position and avoid pseudoscopic images with reversed depth.
