Holographic Waveguide Display With Large Field of View and High Light Efficiency Based on Polarized Volume Holographic Grating

Yuchen Gu et al.

Summary: A polarization multiplexing structure based on multilayer reflective polarized volume holographic gratings (PVGs) is proposed to enhance the field of view and brightness of augmented reality waveguide displays. Through stacking PVGs with different periodic components, the structure increases wavelength and angular bandwidth. Control of liquid crystal pitch rotation direction allows for diffraction of both left-hand and right-hand circularly polarized light, significantly improving efficiency.
