Compact Light Field Augmented Reality Display with Eliminated Stray Light using Discrete Structures

This paper discusses the design of a wearable display in the form of compact eyeglasses, supporting a fair field of view, correct focus cue, and optical see-through capacity. Based on integral imaging, our proposal comprises a discrete transparent microdisplay array as the image source and a discrete lenslet array as the spatial light modulator, without the need for a pre-imaging system or special prism. We designed an annular aperture array to eliminate stray light, controlled within an imperceptible limit. Through a stray light simulation and an imaging simulation, the system was proved to provide a good image quality for both virtual and real information.
