We propose an algorithm that converts a full-parallax hologram to a horizontal-parallax-only (HPO) hologram for 3D display. We first record a full-parallax hologram of an object. Subsequently, we filter the hologram with a Gaussian low-pass filter and a fringe-matched filter along the vertical direction. The final filtered output becomes an HPO hologram. To the best of our knowledge, this is the first algorithm proposed for converting full-parallax holographic information to HPO-holographic information.

We propose a three-dimensional (3D) holographic display by converting an optically recorded complex full-parallax (FP) hologram to an off-axis horizontal-parallax-only (HPO) hologram. First, we record the complex FP hologram of an object using optical scanning holography. We then convert the complex FP hologram to an off-axis HPO hologram through fringe-matched Gaussian low-pass filtering and with the introduction of an off-axis reference.
