Here, we introduce an optical tool, holographic optical element (HOE), which can be applied for AR applications. HOEs are holographic volume grat- ings, which have transparency and distinctive optical characteris- tics. HOEs can perform the roles of optical elements by transform- ing an incident wavefront to a predefined wavefront via diffraction [Close 1975]. Since HOEs are usually recorded in thin film such as photopolymers, they have various advantages in weight, cost, and thickness. Thus, there have been several applications using HOEs, including see-through light field displays [Hong et al. 2014] and head-mounted displays [Kasai et al. 2001].
