Metameric Varifocal Holography

Abstract

Fig. 1. Metameric varifocal holograms. We present a perceptually guided method for phase-only hologram generation for holographic display systems using eye-tracking. Our holograms reconstruct single-plane images at the correct focus levels. These holograms reconstruct high-resolution visuals at a user's fovea while displaying statistically correct content across their peripheral vision indistinguishable from the target images (metamers). We provide sample simulated image reconstructions at two different focus levels at the top row. The bottom row contains zoomed-in insets from these two reconstructions. The gaze location for each reconstruction is provided with a dot. The readers may best view this figure at a 60 cm wide display from a viewing distance of 80 cm. We intentionally choose sparse content as a target image to depict our approach's suitability for the emerging trend of augmented reality displays.

Perceptually guided computer-generated holography

“…Having all these benefits in mind, we derive a perceptually guided CGH pipeline, and we introduce technical details of our CGH pipeline in our main publication. 14 We call this new pipeline a metameric varifocal CGH and built it using our holography simulation library 15 and learned light transport method. 16 There are three primary parts of our pipeline these are as follows:…”
