A Study on Augmented 3D Display Optimization Based on Holographic Optical Element for High Depth and Magnified Image

Abstract

Modern Pepper's ghost—“floating hologram”—systems generally use transparent screens called half mirrors or foils. this system must have the same screen size as the image size in order to display a large-sized image. Further, depth of the image can only be obtained from the distance between the screen and the display panel. These limitations can be overcome using holographic optical elements (HOE). HOE is made by recording as a refractive force of the lens with holographic material. In this study, the numerical values of the reconstructed images were theoretically analyzed through optical ray tracing, and the theoretical design of the reconstructed image size and depth plane was numerically measured and experimentally verified.

Performance Evaluation of Ground AR Anchor with WebXR Device API

“…An HMD that included a head tracker was selected for the ground truth experiment, which showed high accuracy in terms of camera trajectory because the head tracker performed the function of tracking the display device. It has been used in several studies due to its high accuracy within the sensor range [25][26][27].…”
