Realistic Defocus Blur for Multiplane Computer-Generated Holography

Figure 1: Realistic defocus blur in multiplane Computer-Generated Holography (CGH). We introduce a novel hologram generation pipeline for holographic displays that offer near-accurate defocus blur and mitigation of visible fringes in reconstructed images. Here, we provide actual photographs captured from our proof-of-concept holographic display. We capture three components of a color image using a three-color laser light source (473-515-639 nm) using the same capture exposure (20 ms) and laser powers, providing the best visual quality for each case. We later combine three monochrome images into a full-color image in the post-process. The state of the art method, tensor holography [31], offers sharp, high-quality images but with contrast loss. Our proposed method mitigates these issues while offering 3D images with improved contrast, more realistic defocus blur and fringe-free images. In this example, our approach here uses six target planes in-depth. We produced the results for tensor holography [31] with our hardware to the best of our knowledge.
