Abstract
We present a holographic multi-path (HMP) approach to extend the eye-box of the off-axis reflective holographic optical element (HOE) combiners for micro-OLED augmented reality (AR) near-eye displays (NEDs). The compact form factor design requirement highly constrains the eye-box and the field of view (FOV) in the off-axis reflection HOE AR combiners. In this Letter, we show that multiplexing multiple independent optical paths into a HOE effectively extends the eye-box. In the proposed multi-path multiplexing approach, separate partial images of a micro-OLED are routed along the multiplexed beam paths and combined to generate a complete AR image. The experiment verifies that the multi-path multiplexing achieves a twofold increase in the eye-box compared to previous results, enhancing the user experience for AR applications.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
