An AR display system with large FOV based on three-layer volume holographic lightguide element is presented. Each layer of the volume holographic lightguide is designed to offer one-third FOV of the diffraction image. The horizontal FOV of the proposed system can reach 63.9°. Each in-coupler and out-coupler is generated with wavelength multiplexing to record three volume holographic gratings with different wavelength in the same device for color display.
