Abstract

We proposed an effective method of digital content generation for the holographic printer using the integral imaging technique. In order to print the three-dimensional (3D) holographic visualizations of the given object, a printed hologram consists of an array of sub-hologram (hogels) should be generated, before the hardware system of the holographic printer is run. There are mainly three parts related to the digital content generation. In the first part, the acquisition of the 3D point cloud object is applied and the second part provided an encoding of directional information extracted from the 3D object. The array of hogel is generated by implementing direction inversed computer-generated integral imaging plus phasemodulation for improvement of the content generation, and displayed on the reflective phase-only spatial light modulator (SLM) then recorded onto holographic material one-by-one in sequence, while motorized X-Y translation stage shifts the holographic material; so, the full-parallax holographic stereogram (HS) is printed on the holographic material and 3D visualization of the object is successfully observed. Numerical simulation and optical reconstructions are verified effective computation and image quality respectively.
