Holographic near-eye display with real-time embedded rendering

We present a wearable full-color holographic augmented reality headset with binocular vision support and real-time embedded hologram calculation. Contrarily to most previously proposed prototypes, our headset employs high-speed amplitude-only microdisplays and embeds a compact and lightweight electronic board to drive and synchronize the microdisplays and light source engines. In addition, to enable a standalone usage of the headset, we developed a real-time hologram rendering engine capable of computing full-color binocular holograms at over 35 frames per second on a NVIDIA Jetson AGX Orin embedded platform. Finally, we provide a comparison of the efficiency of laser diodes and superluminescent diodes for the reduction of speckle noise, which greatly affects the reconstructed image's quality. Experimental results show that our prototype enables full-color holographic images to be reconstructed with accurate focus cues and reduced speckle noise in real-time.
