Abstract

This paper proposes a new function of the two-dimensional lens array that is composed of many gradient-index lenses. The length of the lenses is an odd-integer multiple of the half period of the optical path. The array produces pseudoscopic three-dimensional (3D) images with reversed depth. Two lens arrays are positioned at a suitable distance so that orthoscopic 3D images with correct depth are formed in front of the lens arrays. The combined array captures, transmits and displays 3D images without other devices. A diffuser or opto-electronic amplifier can be inserted at the specific plane within the lens array.
