Hologram generation from orthographic view images of three-dimensional object and its optimization

摘要

We propose a method for generating holograms of real existing 3D objects without coherent optical system. Multipleorthographic view images of the 3D objects are captured under incoherent illumination and Fourier or Fresnel hologramis synthesized using captured view images. A lens array is used to capture multiple orthographic view images efficiently.We also present a method enhancing the phase-only Fourier hologram. By applying the constraints to the orthographicview images and the generated hologram iteratively, the enhanced phase hologram is obtained.
