Abstract

A novel algorithm for constructing computer-generated holograms using point clusters is presented. This method exploits the precalculated triangular meshes used in previous research and can reconstruct less noisy 3D objects. In addition, the high-speed property of a ferroelectric liquid crystal spatial light modulator is utilized to enhance the reconstruction quality. All 3D holograms generated in this paper are based on Fresnel propagation; thus, the Fresnel plane is treated as a vital element in producing the hologram. A GeForce GTX 770 graphics card with 2 GB memory was used to achieve parallel high-speed hologram generation.
