Abstract

An important feature for an effective display hologram is a wide viewing angle so that the autostereoscopic aspects of holography are dramatically evident. A short conjugate distance between the light source and the hologram can simplify the problem of supplying optimum illumination for display holograms and provide higher illumination intensity. These two desirable features, wide viewing angle and nearby point source illumination, have been incorporated simultaneously in planar format white light-illuminated transmission holographic stereograms made from computer graphics. This talk will discuss design considerations related to these two issues. We have achieved conjugate distances of 15 cm for illumination with a tungsten light bulb and viewing angles >70°.
