The authors propose a new function for a 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 arrays can capture, transmit and display 3D images without other devices. This function is similar to that of integral photography.
