Abstract
Phase-shifting digital holography is a hologram capture method used for natural scenes. We propose a method for enlarging the viewing-zone angle for the electronic holography input. During hologram generation, if we use multiple reference beams or multiple object beams whose incident angles differ slightly from each other, the viewing-zone angle of the phase-shifted hologram can be expanded several times compared to the original. In the experiment, a phase-shifted hologram with a viewing-zone angle of 16 degrees was generated using 3 object beams whose incident angles differ from each other by 5.6 degrees.
