Curved Transflective Holographic Screens for Head-Mounted Display

A volume hologram recorded with a lens array is proposed as a transflective screen for Head Worn Display (HWD) systems. Design, fabrication as well as proof of concept are reported. Light from a projection system, with similar properties to one mounted on the side of an eyewear, is efficiently diffracted towards the eye with an angular spread given by the numerical aperture of the lenses forming the lens array. Using a dual-focus contact lens, high-resolution images can be added to the HWD user's normal vision, as light from the surrounding environment is transmitted through the screen with low aberrations. This screen offers the possibility for small footprint and large field of view HWD's.
