We developed a head-mounted display (HMD) that achieved high levels of color uniformity and optical efficiency. The full-color holographic volume grating (HVG) attached on the specially designed wedge-shaped waveguide HMD system provided a 17° horizontal field of view (FOV). Theoretical analyses showed that the proposed waveguide resolved the problems of thickness and limited FOV. In this system, the HVG was recorded using a special sequential recording process on single photopolymer unit with 633, 532, and 473 nm wavelengths. The results confirm that the designed and fabricated waveguide can be employed in future commercial HMS.
