Paper Abstract

A holographic stereograms generation technique based on multi-view displays does not require diffraction calculation when generating holographic stereograms from multiple perspective projections of real objects. However, a viewing area was limited when the spatial frequency of the quadratic phase distribution exceeds the Nyquist frequency determined by the pixel pitch of the spatial light modulator. In this study, we improved the technique by introducing a spherical lens on the hologram display plane to provide a quadratic phase distribution to wavefronts. Because of random phase distributions that were added to the parallax images to obtain smooth motion parallax, speckle noise was observed in reconstructed images. To reduce the speckle noise, the spatial bandwidths of the wavefronts were limited. The proposed technique was verified experimentally.
