Color multilayer holographic near-eye augmented reality display

This study demonstrates a full-color near-eye holographic display capable of superimposing color virtual scenes with 2D, 3D, and multiple objects with extended depth upon a real scene, which also has the ability to present different 3D information depending on the focus of the user's eyes using a single computer-generated hologram per color channel. Our setup makes use of a hologram generation method based on two-step propagation and the singular value decomposition of the Fresnel transform impulse response function to efficiently generate the holograms of the target scene. Then, we test our proposal by implementing a holographic display that makes use of a phase-only spatial light modulator and time-division multiplexing for color reproduction. We demonstrate the superior quality and computation speed of this approach compared with other hologram generation techniques with both numerical and experimental results.

Automated summary

This study presents a full-color near-eye holographic display that can overlay color virtual scenes with different dimensions and multiple objects onto a real scene, and can provide different 3D information based on the user's focus, using a single computer-generated hologram per color channel. The holograms of the target scene are efficiently generated using a hologram generation method based on two-step propagation and singular value decomposition of the Fresnel transform impulse response function. A holographic display is implemented using a phase-only spatial light modulator and time-division multiplexing for color reproduction, demonstrating superior quality and computation speed compared to other hologram generation techniques.
