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.
