Figure 3
From: High-contrast, speckle-free, true 3D holography via binary CGH optimization
Demonstration and performance evaluation of true 3D holography in 2D near-eye displays. (a) Scheme of Fourier amplitude holographic display prototype. The figure visualizes SLM illuminating light and diffracted light from the center pixel of SLM (dot line). Only red wavelength is depicted for simplicity. (b) Simulation results to assess three binary CGH methods, including superposition as updating random phase (random), Gearchberg-Saxton (GS), binary-SGD (B-SGD). (c) (left) Simulation and (right) experimental results. All results are obtained with 24 TM. The bottom insets are PSNR and SSIM. (d) Experimentally measured PSNR and SSIM according to number of multiplexing. (e) Experimentally measured speckle contrast and its reduction ratio. (f) Experimental image contrast comparisons using the sinusoidal hologram and zoom-in region of (c). Source image by \(\copyright \) copyright 2008, Blender Foundation | www.bigbuckbunny.org.
