Abstract
We propose a holographic 3D display system which can produce images with adjustable viewing parameters and eliminated zero-order interruption. The 3D scene is generated from a 3D CAD tool, and point source algorithm is used to generate the holograms. A two-step model is introduced in the computing to generate precise Fourier holograms. A phase-only spatial light modulator (SLM) is used in the optical reconstruction, which can replay clear images for 3D diffusive objects. During optical reconstructing, the viewing angle and image size of the system can be adjusted by changing the parameters of the replay lens. A filter is introduced in the replay system to eliminate the zero-order interruption and increase the 3D image quality. Optical experiments are performed, and the results show that our proposed holographic display system can produce noiseless 3D image reconstructions.
