One-step method to take IP stereoscopic-picture by using a 2-dimensional concave lens array

Abstract

One-step method to take IP stereoscopic-picture by using a 2-dimensional concave lens array was proposed previously, but the experimental confirmation could not be found so far. In this study, this method was examined, and was experimented with handmade 2-dimensional concave lens arrays. With these results, it was confirmed that IP stereoscopic-picture can be taken with very simple apparatus, and 30 degree of viewing zone angle, which is 1.5 times of that with GRIN lens array, can be obtained.
