Three-dimensional holographic imaging of a diffusely reflective object with conversion to a horizontal-parallax-only hologram

摘要

We demonstrate a 3D holographic imaging system that composed 1. Recording stage, 2. Processing and transmission stage and 3 Reconstruction stage. First, we record the hologram of a diffusely reflective object using optical scanning holography without speckle noise as well as twin image and background noises. Second, we convert the hologram into an off-axis horizontal-parallax-only (HPO) hologram. Third, we reconstruct the off-axis HPO hologram using amplitude-only SLM. To the best of our knowledge, this is the first demonstration that records and displays an HPO hologram of a diffusely reflective object optically.
