Full-color binocular retinal scan AR display with pupil tracking system

Abstract

We have developed a full-color binocular retinal scan AR display, presenting an always-in-focus image to the viewer with a pupil tracking system combined with mechanical movement of an HOE combiner and steering the beam incident angle to the HOE combiner. We achieved high image quality by suppressing dispersion with a relay optical system using a holographic compensator. Our wearable prototype supported a binocular stereoscopic image with 980×560 pixels resolution per eye, 47° diagonal field of view, 6.4×3.2 mm2 eyebox, and mechanical IPD adjustment from 55 to 71 mm as an initial setting.
