Abstract
We present a technique for generating zoomable three-dimensional (3-D) computer-generated holograms (CGHs) using layer-based shifted Fresnel diffraction. The 3-D scene is sliced into multiple parallel layers according to the depth information. Shifted Fresnel diffraction is implemented in calculating the propagations from different layers to the hologram plane with adjustable sampling rates. The proposed method provides an efficient way for zooming 3-D CGHs without optical zoom module. Optical experiments have been performed, which demonstrate the proposed method can reconstruct quality 3-D images with different scale factors.
