Paper Abstract

Usual problem in 3D integral-imaging monitors is flipping that happens when the microimages are seen from neighbor microlenses. This effect appears when, at high viewing angles, the light rays emitted by any elemental image are not passing through the corresponding microlens. A usual solution of this problem is to insert and a set of physical barriers to avoid this crosstalk. In this contribution we present a pure optical alternative of physical barriers. Our arrangement is based on Köhler illumination concept, and avoids that the rays emitted by one microimage to impinge the neighbor microlens. The proposed system does not use additional lenses to project the elemental images, so no optical aberrations are introduced.
