Abstract

Reconstructions of digital holograms have a very shallow depth of focus. In order to obtain a perceptually greater depth of focus, we explored a computationally simple approach, suggested by Lehtimäki and Naughton [3DTV Conference 2007; IEEE Press, New York (Kos, Greece)], where the perceptual depth of focus is obtained by dichoptic viewing of near focused and far focused holographic reconstructions. In the dichoptic viewing arrangement one eye sees a near focused and the other a far focused image. Because of binocular fusion we see a blend of the two images, in which the perceptual sharpness is far more uniform than in each of the images alone. In this experiment, we sought an answer to the question of to what extent does each dichoptically presented image contribute to the perceived sharpness of the binocularly fused image
