Abstract
We propose an optical viewer based on the integral method. The viewer composed of two GRIN lens arrays and a diffuser in between can form observable three-dimensional images of objects. The length of the elemental GRIN lenses that constitute the arrays is three quarters of the cycle of the meandering ray path on the input side and one quarter of the cycle on the output side. By substituting the diffuser with an image intensifier as an optical amplifier, we were able to observe 3-D images of objects placed in a dark space without the use of a camera or display equipment. The primitive experimental results proved the viewer produces three-dimensional images that can be observed. We also describe the visual resolution characteristics.
