Abstract

We propose an eye-box extension method for augmented reality (AR) glasses utilizing a dual-holographic optical element (dual-HOE) and a micro-OLED (µOLED) light source with a broadband spectrum. This scheme leverages the strong chromatic dispersion of HOE to significantly extend the eye-box without compromising AR quality. The proportional relationship between µOLED spectral bandwidth and eye-box size is analyzed theoretically, indicating that a broader spectrum µOLED provides a wider eye-box. Experimental results using a prototype demonstrate eye-box expansion up to 8 mm for µOLED with a 60 nm spectral bandwidth.

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.
