Digital hologram recording and stereo reconstruction from a single hologram

摘要

In this paper we present novel results on the reconstruction of stereoscopic information from a single phase-shift hologram captured using a 2.2 μm pixel-pitch CMOS camera in a holographic interferometer configuration. The low pixel-pitch camera allows the digitizing of holograms with a higher spatial-frequency than what has been reported in the literature, allowing the recording of macroscopic objects closer to the camera sensor. The reconstructed information can be visualized using 3D stereo glasses. Prom the perceived 3D we could identify several depth cues, including the occlusion effect which has not been easy to produce from single-aperture holography. The occlusion effect is also known to be difficult to produce from stereoscopic sources.
