Optical see-through Maxwellian near-to-eye display with an enlarged eyebox
Development of head-mounted displays is critical for improved experiences for augmented reality. Authors Kim and Park build and test a near-to-eye (or head-mountable display) prototype consisting of spatial light modulator (SLM) filtering optics, a waveguide, and a holographic optical element (HOE) to generate the augmented reality images. This prototype seeks to overcome limitations of alternative head-mounted displays, which may suffer from effects that cause eye fatigue, the limited range the eye can move from the optimal position (eyebox), loss in image resolution, high computational load, and/or reflective, opaque optics. The fabricated HOE is designed to create three focal spots with spacing slightly larger than the diameter of an eye pupil, enabling an enlarged eyebox for the device. Results are presented both as static figures and dynamic movies to demonstrate the use of the device to display in-focus images imposed on a natural scene for several operational conditions including a wide range of different eye focal lengths and different eye positions.
